Just as an FYI, most states have programs that will fund a disability lawyer to assist you with your disability claim. Most of the time the lawyers will be paid partly through your claim if it is successful and it's usually free if it is not.

Also do not get discouraged if your claim is initially denied, in my state it's basically an open secret that your first claim gets automatically denied to discourage people from actually getting benefits. With disability, it's all about persistence, documentation, and filing as soon as you can. Even if you get denied for years, when it is successful your claim will be back dated to the date of your initial filling.

Not a lawyer, but I work in a field where most all my patients are on disability, and I have had to help my parents file in an extremely conservative state.
