I've just gone through the process, successfully, after reading up a lot on what gets approved. I'ld say your case might seem a bit thin to the SSA right now. One of the things they like to see is an effort to get rehabilitated. Repeated failure strengthens the case that you can't work. But you might surprise yourself. The younger you are, the more possible it is that you might learn to cope, despite your bipolar condition. Just having that as a diagnosis is not considered disabling by the SSA. Many people with bipolar disorder work successfully.

I highly recommend working with a law firm. I used one of the nationally advertised ones that specializes in SSDI. If you call one of these firms, they will give you an idea of your chances. Basically, they won't take your case, unless they think you have a winning one. The law firms that I talked to seem to be very interested in how much medication I was on. Also, they are apt to ask if you have a doctor who sees you as disabled. (I did.)

Do establish a paper trail documenting treatment of your condition. Someday, that could prove invaluable. It did for me.
