It is so difficult. I feel the same about my son. He is at home and I am doing everything I can to help him stop taking drugs. He is 26. There is just the two of us. Like you I feel such a failure as a mum. I can’t imagine how much your heart is broken having not only your daughter but a grandson who is in a bad way as well. I don’t think people understand how difficult it is for mothers to see their children in such a state. I wish I could offer some hope but I don’t have any.
