I'm looking for some advice on how to get through to my 17 year old DS. He's always been a bit moody, but normally bounces back quite quickly. However for the last week he's been really quiet and withdraw and flares up if I say the slightest thing he doesn't agree with. He's normally pretty social but isn't going out at all, just sits in his room, either on his phone or on the PS4.
He's finished college until September now, is looking for a job but no luck so far. I've tried to involve him in doing things with me but he's not interested and won't talk to me and says nothings wrong.
Clearly something is wrong, but I've got no idea how to get him to open up. So should I just leave him to it or keep trying? I'm getting sick of having my head bitten off, but at the same time I'm worried about him.
