my son is 19 but still lives at home. He's at college - but hardly goes and is failing - I am leaving him to fail and have stopped asking him. He is smoking weed - says this helps him relax and switch off (he has dyslexia) - we are pretty open minded but worry this may escalate if it hasn't already. He is going through a stage of sleeping most of the day and up at night. He has left home once (after he argued with his dad) but came back after a week. Just left again today because I woke him up at 2.30pm as he had asked for help to fix lights on his car. We try not to provoke and engage him in anything and generally tip-toe around him. He rarely eats with us. Keeps saying he wants to commit suicide but won't see a councillor- has never actually tried it. But can't seem to cope with life. Example of his behaviour - went out for a meal for my birthday, because I ordered food for us all to share he suddenly snapped into a mood. Said he wasn't hungry, sat there on his phone. We ate quickly left. He drove off on his own. He is spoilt. He lies. He gets money (from somewhere)? He says he is angry inside (he isn't to us) He can be incredibly sweet sometimes and I try to positively reinforce this when he does. we are hoping in time he will grow up and find his way. I worry where all this is heading..
