I am not sure how things work where you live, but if you were here in Canada I'd suggest going on welfare or collecting employment insurance while you apply for disability and during the waiting time. I am not sure how your location works but is there some sort of welfare-type social program you can go on, or employment insurance you can collect, while waiting for a reply from disability? With a diagnosis like DID and if you have good psych referrals you have a good chance of being accepted, I think.
