Crazy Scientist,
I was discussing your case with my daughter this evening. She helps a lot of people who suffer from the after effects of stress, including PTSD. She immediately recommended that you should seek help from a well accredited trauma specialist who might have enough clout to convince your AME and the CAA that you are no more a risk than anyone else but also take some of the responsibility for the decision to let you fly.
I hope that it all works out well for you.
