Well, it took all of six months to get benefits for me, but I have a physical disability that's pretty hard to miss.
Medicare takes two years, but isn't Medicaid an option? If you're American? I know requirements are different from state to state.
Also, for those on meds, check with the drug companies and see if they have a program to pay for meds for low income people. I had to do this (one of my drugs is 1600 dollars a month) until my full coverage kicked in. Usually it's a straightforward form (one page) to fill out, and the company usually requires financial proof (the letter with your disability award-I think for one company, they needed verification of yearly income as well).
I hope this is new info for some of you and you can use it.
