Disability is very hard to get, almost everyone gets turned down the first time, no matter what the diagnosis. Mental illness is the hardest to get because there are no definitive medical tests to back it up.
My pdoc got me ready for all of this, so I wasn't surprised at all. Even tho I had been her patient for 8 years and she had been telling me for three years I MUST stop working, I said No Way, I'm not disabled! I didn't want to quit working, I loved what I did, but I admit the stress of it was way too much and I was hospitalized twice in the span of a 1 1/2 year period. I am a VERY strong minded and stubborn person with an abundance of pride. But, finally I had to agree I could no longer handle it, even with frequent changes of jobs, always looking for that less stress. I supose I brought much of it on myself, I just automatically overachieve and am an extreme perfectionist. If I made ANY kind of mistake, I would obsess over it for days, lose even more sleep than usual and think of it 24/7. I coudln't change that. So I finally gave in. Got rejected, my pdoc said most don't get anywhere without an attorney, so I hired one over the phone, and 2 months later got my first check. I had not been working for 2 years, thinking I would go back, and still didn't apply for SSDI, so they paid me retro, my check was for 14,500. (The attorneys take 25% off top). I paid off my SUV I had bought 2 months before I left work, and blew the rest (bought a show horse, all the trimmings and other s**** to go with it, and then about 37K on credit cards on stuff I don't even remember, I dont have much to show for it because I still refused to stay on meds).
OK, sorry I rambled, you know by now that's what I do, lol, but that's my experience with SSDI and pretty much everyone''s. I suggest you get a lawyer involved, or the usual wait is a year or more. Sometimes less, of course, you just never know. True, your age will help.
Just an aside, major depression is every bit as much of a qualification as BP whether the patient is "in love" with their diagnosis or not. And there are people in CA who get disability, Sandra is saying it's harder to get there, and that is probably true.
