hi my son is 37, and is on coke and other stuff, he also has a problem with drink. he has a young son that his partner has stopped him seeing. me and my wife have tryed to help him with work, somewhere to live as he keeps messing up where he stays and they through him out. it has now got to the stage where every thing is my fault. he wants to hurt me and put me in hospital. I try to reson with him and help him see his son but iam still no good. iam at the end of my tether. any advise on what to do.
