Hey there,
Sorry, you feel frustrated, I don't blame you. When I was on SSDI for my MS I had to file for reconsideration with a lawyer also...6 months later I got approved and received a big back pay check... It is very common to be denied the first time around, it's not right, but VERY common. Some of us just have to fight our asses off for what other people seem to get handed to them.

(((((HUGS))))) Have a good day also!
