I have a friend who thinks a man(vocally) is possessing him. He believes this man makes him gag and screech. I notice it happens when he is stressed: ie talking on the phone , discussing the topic therapy(other than medication), when someone tries to gently tell him that this voice is unhealthy and to disregard it, and so on... He lives in a place where his medical health is somewhat overlooked and needs advocates. If anyone has any advice on how he can overcome this ( such as insisting on therapy or anything ) that I can bring to his "guardians" it would be greatly appreciated. Good luck and best wishes to all.
