I'm at my wits end. My 17 Yr old ds has been going with a girl on and off for 2yrs. She is a very damaged girl from a family of drug addicts, younger siblings in Foster care. First year they were together was OK - he thought he could save her. 2nd year, her aunt died of drug od and she went off the rails which coincided with her turning 18 and taking the attitude that she could do what she wanted. My ds could not cope with her running wild and drinking heavily. I also suspect she was taking drugs. He struggled through his gcses as she dumped him 2 weeks before. They got back together but it has just been a constant mess of violent arguments and my sons mental health has declined in the last 6 months. I believe he is suffering from anxiety and possibly depressed. He loves her so much but wants to control her and have the girl back that he fell for but that girl is long gone. He is failing in college, he has stopped seeing his friends, he is withdrawn and isolated but also so agitated. I fear for him. He is on the waiting list for cahms but in the meantime I he is starting counselling with a local mental health charity. Tonight I have watched him have a phone conversation with her and he looks to me like he is a breaking point. I do not know where to turn anymore.
