I GOT it the first time and here's how:
Rather than going in to tell them how disabled I was (knowing they wouldn't listen)
I had all my medical records for them going back to the microfilm they still had from 1977. There are certain words that generate almost instant "yes." One is bipolar. Another is "cognitive disabilities not otherwise specified." I don't know the other ones, but I had no trouble. I think it's hard to get SS with PTSD, ADHD and CD. They want to think you are incapable of EVER working. I also had a long history of failed jobs, plus a Job Assement, which said I'd need a Job Coach, but that there isn't one. Still, I don't present as being disabled.
Can't tell you how shocked I was when I got my letter!
They must *really* think I'm a hopeless case...hehe.
