Talk to a lawyer before you do anything. See what the disability lawyer has to say about your chances of getting disability.

My Doctor suggested I should think about going on Disability.
Everyone is different. You should know if you can do your job.
My memory started to fail.

I had to get a lawyer for my disability.

Agree, but check with an attorney. I think Parkinson’s diagnosis might be on the list of automatic approval

Thanks for the advice.
