Investigated by the FBI and keep screwing up even though I know they're watching. What do I do after everything I've done?

I was in a permeant anxious/psychosis issue with my consciousness and failed every morality test they gave me , but now I'm doing slightly better(Dr won't give me Xanax and Ritalin).

What can I do to prove I'm not a danger to myself or anyone else and show remorse for my actions? I was off my medication then and not thinking clearly but now I'm on it and doing slightly better but not fully all there in the head.

Im probably looking at life in prison, I think but not sure that I made threats, I have two weeks or a month where my memory is a blur.
