Hi, please don't shoot me for putting on AIBU but I have a time sensitive issue. This is a long one but I thought a back story would help. 3 weeks ago after my son had been here with friends having a drink in the room my ex built on the side of the house, I've been quite happy to let them go in there,pool table, dart board and a couch, my son is 20 years old and I don't mind them being in there as they have never ever been any bother. My son was always quite a lonely lad who spent most of his time in his room on his computer or with me and his dad. A nice kid though, his dad left 2 years ago and he had a shit time and he was really angry which I took the brunt of. He then got chatting to a few lads he had been in middle school with now and over the last year he has really started enjoying his life, going out and basically doing what he should be doing. So 3 weeks ago I found a white little packet on the floor, drugs and I was in complete shock, I never thought in a million years he would do that. My sister had a year in rehab for being addicted to cocaine and her daughter moved in with us, he saw the pain first hand it caused. So I asked him when he woke up what was he thinking, he informed me it was ket and not cocaine. I was in tears telling him how he is my whole world and if anything happened to him I would just die, he was in floods of tears and promised me it was the second time he had done it but he would never, ever do it again he was genuinely upset. So he went out last night and had his friends back and he fell asleep on the couch, his jacket was soaked through so I emptied his pockets and found another bag of this white powder. I'm devastated and really don't know what to do, he's still in bed but is getting up at 5pm to meet friends again. Could anyone help me with what I should say to him, I don't know how to handle this and I don't him not to feel he's not able to talk to me if I handle this the wrong way. We have always been close and his dad leaving really up ended his life, we have been there for each other throughout this and I feel I must have done something wrong, let him down for him to be doing this. I'm scared he will end up like my sister. I'm sorry this has been so long but I wanted to get the whole picture across. If you have got this far then thank you, I just need to know what to say to him when he wakes up.
