My 18 yr old ds came home from college yesterday, went straight to his bedroom, jammed the door shut and hasn't come out. He hasn't eaten or drunk. Won't speak to me at all apart from telling me to piss off when I offered him food. He starts his A levels next week. I phoned his gf's mum this morning, turns out his gf split up with him yesterday (great timing...not) after 3 years together. On top of that he has AS. What can I/should I do? Feel v helpless. Just left two bottles of lucozade outside his door, at least he wont be dehydrated!
