I applied for SSDI/SSI 1 1/2 to 2 yrs ago. I was denied my first try and then I got a lawyer (Binder and Binder). I was denied a second time, but my case is different. I have never worked and am young. I went before an ALJ and he gave me a fully favoriable decision. I also recommend getting a lawyer, it just makes the process so much easer for you. I never had to do anything, they took care of it all for me and called me once a month to tell me where my case was and answered all of my questions. Good luck!
