Have had awful 18 months with DD (17) including an overdose and serious self harm. Things have been a bit better recently and she is due to start a new job tomorrow. Today she appeared to be slurring her words and I thought she might have been drinking or had taken something so when she asked for a lift into town to meet a friend DH and I refused to take her. Cue huge row, smashed up her room and drank half a bottle of spirits. At some point she self-harmed again though not deep cuts. Then lots of tears, after which she asked for a lift into town again! Refused again and after a while she walked into town herself. I suppose we could have stood in her way but to be honest, I think it would have become violent if we had as I was as close to losing my temper as she was. She has since texted to say she is sorry, and that she is safe. She hasn't been violent like this before. What the hell do I do now?
