how do you help a teenager feeling like this?

[brizzlemint]

I got home from work and my teenager was OK, a bit quiet but then he was chatting to his friends and playing FIFA. I asked him if he'd picked up the parcel with his new clothes in and he hadn't been to look in the garden for it so was told to go and look. He lost his temper with me and said it wasn't there - turned out DD had put it in the cupboard - and starting calling me all kind of names under the sun, for which he was told he wasn't allowed on his Playstation tonight.
He came down from his room having clearly been crying and told me that school was hard and he has a German exam tomorrow and he's worried about it - he puts a lot of pressure on himself to do well.

I'm at a loss how to help, what would you do?

It’s still not acceptable to be vile to you. Has he actually apologised or just tried to justify his behaviour?

Suggest an apology is needed and you will make you both a cuppa.
Don't shoot him down for actually confiding what is wrong.
Outburst or not he opened up.

That's tough going for a teen.

He hasn't apologised yet but he will when he's ready - he's good at apologising once he's had time to calm down. He's been down and listed why he's stressed (basically a list of what he had to learn - he's obviously learnt it if he can list it all like that!) and gone back to his room for now.

I wish he'd learn to open up before the outburst.

Something nice to eat, a chat and an early night.
