your best bet is to have a free consultation with a lawyer or lawyers, who specialize in Social Security Disability Insurance. You can find them in the yellow pages. Someone who previously worked for social security would be an additional plus. They would better be able to tell you if your psychological disorders that limit your ability to work gainfully and function in a work environment are limiting enough to qualify you in your particular case for SSDI.
Some of the previous answers you got here in this thread,may not fit your particular situation and may well not be valid for you.
