just my 2 cents. after all the psych drugs i took. i dont know what they did to my body let alone my mind ? it sounds to me like he's had a nervous breakdown. as with myself after that theres no turning back. there is no fixing a person after that. other people around you have to be very understanding and patient. thats when true love comes in. if somebody does'nt understand what the other person feels they will never understand or get it unless they experience it for themself. best of luck
