I can relate to your plight. I was raised in a Scientology family, which often left me feeling an outsider to all non-Scientology social sets. I became just as alienated from Scientology in my late teens, leaving me totally socially isolated, alienated from most lifestyles and career choices, and worried about how to make my way in the world. I spent a lot of time "drifting" as they say, and wondering what in the world I was going to do as an adult and how I could start living independently. Any non-Scientology relatives I had were too remote, too lacking in resources, or both, to help me. I'll skip over things that didn't work well and give some highlights on what I learned about digging out of that rut:
1. Really desirable jobs are seldom advertised, but a fallback jobs/job skills that match frequently advertised positions will almost always include bookkeeping and accounting - with computer skills to do it modernly. Throughout my life there have always been advertised slots for skilled accounting clerks/bookkeepers in any newspaper want ads I've ever read. It's a good safety net to focus on getting some education and job experience in bookkeeping/accounting. I gained enough qualifications to be offered some very desirable accounting clerk slots merely from adult night school offered by the local high school district at very little expense. It you take these subjects in a step by step way you can acquire the necessary skill. You may never get rich working clerically in an accounting department, but they often turn out to be living wage jobs very much worth having.
2. Really desirable jobs are seldom advertised, but you can bump into them readily if you work through a temporary service and show a good work ethic and cheerful approach to all tasks. People often try to fill positions important to their company, if on a level that can be done by temps, by hiring a succession of them and observing each of the people reporting to the assignment to see if there is a good candidate. This is a more certain way of hiring the right staff than advertising for a job and relying on brief interviews to sort out the genuine prospects from the suspects. If you have computer skills, and especially accounting oriented computer skills like ability with spreadsheets, double entry computer programs or such, working as a temp for about a year should land you at least one great offer of a stable job that pays a living wage.
3. If desperate for a job, simply go door to door of the businesses in town and ask if they need any extra help at times. Don't wait for advertisements or invitations. Take care to mention that you are in the process of canvasing every business around to see who needs help. "Anything the rest of the staff likes to avoid doing, for instance." There are always tasks in a business people try to avoid but are in fact important to do or else management wouldn't create the task in the first place. The law of averages says you'll get some luck with this approach, even if it is merely a referral to someone else who might be hiring a "go-getter" like yourself. This can generate survival cash and often lead to a very desirable offer somewhere. This approach of (1) bravely canvassing everyone and (2) having a good attitude about whatever the task may be distinguishes you from other job seekers who aren't as brave as that, and it impresses the hell out of many employers to meet someone who actually will do this. The key is to carefully not intrude upon the decision maker of the business when with a customer or otherwise clearly too busy, to be cheerful and upbeat about the conversation and to accept gracefully any answer. You often can find people will refer you to someone who does need someone like you to help out, though they personally don't have need of extra help at present.
4. Seek to live at first and for a while after leaving home in a rented house with many housemates, preferably in a college town if you can. Skip studios and apartments - go for the jointly rented house. Trying to afford your own apartment sounds like the next step from living at home, but there is an IMMENSE advantage in mingling with about 4-5 other housemates PLUS whatever social networks they may have going. I first did this simply to afford rent after living in very unsatisfactory conditions on my own, and found out what a life changer it can be for a young adult to live with a large set of housemates. Even a meager McJob wage can help you afford this kind of living. The real boost it gave me was to see that other people's lives seldom follow stereotypical scripts that you might think you need to follow for success and independence. Real life happens to people with stellar academic records and bright prospects who need to interrupt their lives for a rehab visit, and real life happens to people who you'd think have meager prospects but are brave enough to get out there and scratch and are envied for the opportunities they find by those people with stellar academic records and background. The experience of living with 5 other housemates revitalized my entire life. I moved beyond being someone originally alienated from the "wog" world by my upbringing and alienated from the Scientology world because I detested its corruptness and how often it attracted unscrupulous and callous people into it. I went from that to someone thrilled with all the prospects before me. I actually decided to go to college from this first experience.
5. Be willing to try out the conventional "helping" sets in society. This includes psychological counseling agencies that are often priced on ability to pay, and various religious groups who offer introductory classes in their denomination's views or other forms of initial participation in activities.
You'll find some religious groups show you very promptly that you want no further contact with them, but simply break off contact with them. Groups with Scientology's leach-like grip on anyone in reach is not a universal trait of religious groups. This broadening of religious exposure is helpful to you, if for nothing more than teaching you that there is a vast pool of people out there injured by their own families religious background, which wasn't Scientology. You are far from alone. It can teach you that there are so many unprovable religioius ideas out there that Scientology's little package of them aren't that important to fuss over. The real point is to commit to principles that you feel make you a good or better person. And actually many religious people are not doctrinaire so much as practical about life choices and their consequences. Many of them are genuinely helpful, even if the help is imperfect.
It was a very big step for me to actually visit a licensed psychologists and then also a psychiatrist for medication to help with the depression I fell into at one point. It was worthwhile though, and I found all the indoctrination I'd received about psychs as willing to do anything underhanded to seize control of you are nonsense. Modern therapists are about "client centered" counseling and bolstering independence, not trying to take over your life or deride you for religious background or beliefs.
The above 5 points are what I'd write to myself as a young adult if I could as the very best advice for how to dig out of the raised-in-Scientology rut and achieve an independent and worthwhile life. I'll mention in addition, though, that I think you should simply stop talking about Scientology with people. Their opinion of it doesn't matter, there are a lot of assholes who aren't the least bit interested in being helpful about what you have to relate in the first place, and frankly what is behind you in life doesn't control your life going forward. Also, accept that your dad is kind of a judgmental and stingy prick. There are worse character flaws in life and worse fathers to have than that. Also, IT ISN'T NECESSARY FOR YOU TO HAVE GOOD COMMUNICATION WITH HIM - because judgmental and stingy pricks are never really good for you in the first place. Do not let a relationship with any other person be the critical test of whether you are going to succeed in life the way you wish to. Your life doesn't revolve around improving your relationship with your father, it revolves around improving your life. Let years pass, perhaps even a decade, and notice if he's interested in improving relations with you on his initiative. If not, then just accept that no one was ever dealt a completely winning hand in life, there are always bad cards dealt you, and having this as your father is simply one of them. Focus on something else to make life fulfilling. He may, though, be willing to help finance your education or other efforts towards independence if he sees you making a serious well planned effort, even if he is a prick generally. It has to do with motives almost all fathers have, callous prick Scientology fathers or not. And this may sound hard or harsh for me to say, but there's merit in not teaching someone "learned helplessness", like simply giving them cash despite this not being critical to support some earnest effort they are clearly making to become independent. Your father may be doing you a favor in not being as generous as you'd like, though its a favor that is kind of hard to receive.
Perhaps on a final note, "real life" happened to me by getting severe depression after everything was starting to look so great for me. As I related, living with a large bunch of housemates and enjoying each of their social circles revitalized my life immensely. I went on to college and wound up graduating with top honors from a respected university in a very difficult area of study. I had been a mere drifter uncertain if I really even belong in this world just a few years earlier and had become someone who felt immense pride and self-worth when I graduated. I had enrolled in each semester of college certain that this next one would be the one to kill my dreams of becoming highly educated, but fought like hell to make it through each one as it came along, and surprised myself by actually succeeding and getting a degree. The economy I graduated into was abysmal for someone of my qualifications, wasn't hiring and wouldn't be for person with that type of education for years to come. After a while I began to wonder if struggling to make something of myself wasn't a stupid thing to have done and if maybe there really isn't ever a way for a person like me to find a place in the world. Maybe just killing myself was the best choice, and I'd have realized it sooner if I wasn't deluding myself about ever being able to fit into the world. Depression strikes many adults at some point, often for no really good reason, and it can be fatal sometimes. It isn't something that you can just snap out of or somehow shows you have defective character, etc. Make plans for how you might cope with it should you encounter it, which you might as the next phase of your life just after something great is achieved or happens for you. Downloading off the internet a book on "cognitive behavioral therapy for depression" from a torrent site or Googling this topic to find out about it is probably the best thing you can do to prepare for this possibility. "Cognitive behavioral therapy for depression" is an amazing advance in psychology that is almost as effective as drug therapy for digging out of depression. I'd recommend it as reading for everyone, either as a fallback for themselves or to point out to someone who needs it so they know about it.

Try to think of it a bit differently. When you make a mistake, recognize you can do something about it, do something different. Change horses, and go another direction. Make amends,if necessary. There are repercussions for some mistakes, but most young mistakes are minor and correctable, without lasting effects. And youth is the best time to do it, but it can be done at any time. How else are you going to learn? 
. After being ripped off by scno/co$, I can see how one would be gun shy about ever 'paying' for 'help' ever again. Fair enough. So find someone trustworthy, NOT A SCNO, and talk through what is going on with you. It will become more clear, and you will feel more secure when you can air out your fears. If you disguise your identity, 
change names, date, ages, sexes, and jumble up circumstances a bit, etc., you can write about it here with some sense of safety and protection. It's OK to lie to protect yourself, your identity, in this case. 
Better than your dad. 
OUTSTANDING ! THANK YOU FOR SHARING THIS.
