As a wise baboon once said...
"Oh, yes. The past can hurt. But the way I see it you can either run from it, or learn from it."
So, what that means is not to keep ruminating about the past, or avoid confronting it altogether, but learn from it so that you'll be better prepared to handle such situations, should they arise again.
If I were you, I'd stop focusing on moving out so I could seek treatment and get myself together first. THEN I'd take the whole "moving out" concept off the back burner and focus on that once I'm better and able to tackle more appropriately.
You say you are on the ASD Spectrum, right? Does your country have special needs programs for people who need a little something "extra" in the way of treatment, and some means to help those who need it with becoming financially independent members of society?
I think that your first on getting treatment is to look for these programs and institutions that help people with disabilities like Aspergers and whatnot. They're out there, I think. You just have to look.
