I don't really have any advice for you. I have two friends who are on SSDI, one for bipolar, the other for a hip issue. I know the paperwork can be really daunting, but you're allowed to bring someone with you to help out, and I think the SSDI people will help you out.

I too have not told many people IRL. My husband also does not really accept that I have a mood disorder, but he is supportive of me doing what is going to help me.
