Hi Faith,
I have been through what you have. When I first applied, I was turned down, went to (their) doc and (their) psych. I was turned down again.
I then hired a lawyer and finally got to go before the judge. He approved me within ten minutes!!
I have spinal issues but he approved me because of my depression!!
Don't give up!! That's what they want you to do!! I bet when you go before the judge, you will be approved and then they will have to pay all the back pay from the time you applied.
Good luck,
Linda
