This is so similar to one of my sons as a lot of you know. In and out of trouble, prison, smoking weed, kept not turning up to jobs because he was stoned , sleeping on mates sofas..... he lives miles from me and didn't want to come and stay with me - wanted to be near all his troublesome mates. Really came to a head about 6 weeks ago when he fell out with his mates mum where he was staying.. which is an absolute dump anyway!! He had a bit of money by then but just couldn't see a way forward as again he's been smoking weed. I spent 4 hours on internet trying to find somewhere he could just rent a room and where they wouldn't want references etc. Finally found one a mile from his mates.spoke to owner, sent my son the phone number and address and said get there within the hour- just have a look! He went, saw for the first time he could have his OWN little space and room and took it on the spot. Has changed him beyond belief. Sometimes you have to hit rock bottom
