Can my sociopathic ex husband fool even the doctors?

I hear you I am dealing with one of those to, I think it comes from his childhood, get this he OD on drugs to kill himself and got sent to the city for an evaluation and they let him go the same freakin day. He is a great manipulator, Now he is back on the drugs and by court order I can't even keep my kids from him, Because he somhow brainwashed the courts! I know from spending 8 years with the *** he is physco and a drug user and he seems to be able to get away with ANYTHING!
