I applied for SSDI, SSI, and my state insurance plan this summer/early fall. It's a helluva process, but I realized that if I have to drop out of school due to instability, I would have no insurance. Also, I've never held a full time job for more than a few months, and my part time jobs are all I have been able to do since I was 18. All this time I thought I was lazy or a loser, now I get that the stress of PTSD and extreme moods were beyond my control and will likely continue the sad track record.
I had 10 jobs in the last 10 years (breaks in between for school). I had to rummage through old tax records to get the dates right. I've also had around 10 doctors in the past year. Had to fill out pages of my daily activities and how my disability affected my quality of life, so did my partner (I guess so they could see if I was delusional). What else did they need? Oh, you have to complete things online that are really long. Blah. Starting the application is easy though. It's like 1 page of info online, then they give you a case number.
SSI takes 160 days currently before you get an answer. Not sure how long SSDI takes. I forget. I got a positive decision for the state's disability insurance. So it's likely I'll get SSDI. All the release forms to my providers were a pain. So it goes.
If not for being manic for 9 weeks, there is no way I could've done all that.
I'm glad you have someone to help you. If you have any questions for me, I'd be glad to help. PM me. I have copies of everything I turned in.
