Our 32-year old son has had problems with addiction, and he has been unemployed except for occasional temp jobs. He's worn out his welcome at most of the temp agencies in the area. He is now homeless but constantly at our house, eating, sleeping, and combative--arguing to the point where he has affected our health, both physical and mental. He is a constant source of stress to his younger sister, who has emotional problems related to anxiety herself. I'm afraid my husband will become seriously ill, perhaps have a heart attack, because he complains about pains in his chest whenever our son is here. It's difficult to get our son to leave. We intend to rekey the locks and if necessary, get a TRO to keep him at bay. We want to help him, but he refuses to help himself to any source but us. We are at a point where we need to take drastic action to remove this extreme stress on our lives. We need direction here to better cope with these problems and hopefully guide our son (although the latter may not be possible) in a more productive way. He has always been a challenge, went to special schools and care. We arranged therapy for him but he refused to interact with the psychologists and psychiatrists. When he turned 18, there was nothing else we could do to convince him to get some help. The situation has just become worse. What now?
