First a little history. Our son came home for Thanksgiving during his freshman year in college, went to a party got so drunk that the next morning while attempting to drive home he ran into a tree. The next three years were spent in court trying to keep him out of prison. (they charged him with a felony DUI as his friend in the car had a minor injury) We had a plea deal and because he was heading to medical school after college his record was expunged upon graduating college. Anyway, after spending a ton of money, time and energy we were moving forward. He returned home, studied for the MCATS had a job and even took a phlebotomy course. After he passed the MCATS he unraveled real fast. We had purchased a beach cottage that we were renovating and he begged us to stay there during the renovation. He found a girlfriend which I believe was his first love. He began an obsession with snap chat and instagram and called himself CreepLord!!! He posted bizzare content and continues to post up to 75 times a day. He quit his job and refused to pursue another one. We were so bewildered by his sudden bizzare behavior. After the breakup with his girlfriend his manic behavior turned hostile and aggressive. We went to a psychiatrist who agreed he sounded bipolar. We insisted he go see him as well and take a drug screen which was positive for cocain. He went to the doctor who called us and said he was not bipolar. He is able to go to the hospital and follow physicians during surgeries lasting 16 hous and behave himself and act perfectly charming. But at home he is hostile, aggressive and threatening. He dropped his medical school applications and says he wants to wait a year.(no problem we only spent 8k on application fees) He talks so badly to me and his father! We were so close before all this and were very good parents. I have had enough of the abuse and finally got his father to agree on taking his car away and deleting the data from his phone. I kick him out of the house but my husband keeps letting him back in. He parties every night, takes adderal and coke recreationally, has lost his really good friends, hangs out with losers, etc. So while I am from the tough love stance my husband wants to deal with his behavior in a "loving" way by getting him out of this element saending him to medical missions etc. Opinions please?
