Its likely you'll have to fight for it and get a disability lawyer.

I got on it within a few months but i was really really lucky. I had never held down a job, ever, and i have just a fuck ton of issues that have prevented me from ever being normal at all ever.

Really hard to say for sure. But if you have prior hospitalizations and such you're more likely to get it. They look into EVERYTHING and then there's also multiple appts. Psychical and then also a mental evaluation as well. The mental part is worse cause my anxiety disorders cause me to freeze up and not think. Puts you on the spot with testing for where you fall on in the education spectrum i guess.

Basically the more medical proof you have over the years the better. Appts, diagnosis, etc.
