Fuuuuuuuuu... I've been screwed and I need your help

Well, I really hoped it wouldn't come to this, but I don't know where to turn.

I've just been kicked from my mom's house. I'm 20 in October and already in deep financial ****. I HAD a plan to get out of debt, get my website up and running, and have a great WSO in mind for future, but I can't do any of that right now because (!) our strained relationship has finally broken.

This is not some petty argument blown out of proportion, so let's please skip the patronizing "it's hard for teens and parents". At worst, parents should be just annoying - can't stay out till 5 AM or get your nose pierced. I discovered from a very young age (try five years old) that I cannot have a simple conversation with my mother - everything I'd say would be used against me later. For quite sometime she's lied to me, stabbed me in the back, spat in the face of my hopes and dreams, and made it quite clear that she really has no faith in me succeeding in life. She's also arrogant and thinks she knows everything about life in money... despite the fact she's got 20 years of law experience, making $40,000/year AND is $20,000 in debt. She talks forever about getting another job, but won't do it. She's also the kind of person who spends hours on hours highlighting self-help books, but never actually does anything the books suggest she do.

I don't have a dad to run to, either. I thought I did for the first 11 years of my life, before everything about his past came exposed to the light and he was officially diagnosed as a sociopath. But we're not here to talk about him.

I've been described as the "black sheep" in my family on numerous occasions - different clothing style, different music, different religion, different fill-in-the-blank. I'm sure all you successful Warriors out there know how hard it is to explain Internet Marketing... well, not only do I just look different from my mother, but I don't have the same plans in life. I take college courses that I WANT to take, not courses for a degree that I'm not interested in and will pay me very little. I'm moving towards bigger, better things. I live life TODAY, and live it to the fullest. All of the above threatens her world-view, and now that she's given up on making me be like her, she's all about control control control.

I stood up to the constant jerking around, and where did I end up? At my boyfriend's house, staying in his sister's room (he's still at home). I can't stay here forever though. He works in an extended stay hotel where he can get me a place to stay there, $800/mo with of course, full furnishings, internet and cable. We plan to get an apartment eventually anyway, so this is a place to sleep for a few months.

Now here's the kicker: I barely make $500/mo at my current retail job, he makes about the same (as most of his money goes toward his car, he's constantly broke). I'm looking for a second job. I'm in debt. I'm still buying a car from a (now former) neighbor but now those payments are pushed further back. I don't even know if I can pay hosting for my goddamn website, which I REALLY don't want to give up as that would mean I'd have to start from scratch again.

Suggestions? Advice? HELP??

EDIT:

To seasoned and Kay King:

The whole "let's knock the young ones" has been done to death. I'm sure you had the same wisdom at your ages as you did at 20. I asked for help. Don't like it? It's called the Back button.

Now.

I'm human. I've f***ed up and so has she. I'm not perfect and I can admit that. I also know that age does not guarantee, or equal, intelligence or maturity. I've seen mature 13 year olds and highly immature 30 year olds.

I don't need personal attacks. I need to know where I'll sleep and how I'll feed myself, kthx.
