I got SSDI very quickly, although I was hospitalized over 12 times between 2011 and 2012. It is easier to prove a mental case than physical according to my friend who works at the local SSA office. However that being said, I had a ton of formal documentation, PDoc reports, med reports etc from all the hospital stays. Now since then my formal diagnosis changed from Bipolar to Schizoaffective. I currently work, very part time using my ticket to work. I wish you the best, but you really need a lot of documentation when it comes to a mental case with the feds.
