Trouble getting along with people is one of the best things you can discuss very fully on the questionnaires that SSA will send you, if your pursue getting disability. If a lawyer thinks it is worth pursuing, then you do have a decent chance of getting it. Lawyers can't make money helping you unless, and until, your claim is approved. They don't like to waste their time on claims with less than what they see as an 85% chance of winning. So take heart. A history of job failures is also an excellent thing to disclose very fully on the questionnaires. The government doesn't really care how much a person suffers from a diagnosis. They only care about how it hampers you holding down a job.

A diagnosis of "psychotic disorder NOS" by a therapist won't impress the SSA very much. Now, that same diagnosis by an MD would carry a great deal of weight. Testing may shed some light on things. I don't think that the SSA considers anything diagnosed, until an MD - ususally a psychiatrist - signs off on it. The best thing you can do, if you want your claim approved by SSA, is to establish documentation of medical evaluation and medical treatment. That means MDs and medications. I went through the process not too long ago.

It sounds like you've been very distressed lately. I hope that eases up for you. If you have a chronic problem, you may have to manage it over the long term. Going to get evaluated by someone is a step toward that. It's good that you do have people around you that care for you.
