I've found that with both my teen girls, too. Fifteen to seventeen was vile... seventeen is much more peaceful.

I can't remember the name of a book I read but it's about the stages of adolescence. They warn that at eighteen, there can be some regression back to self centredness. I have certainly noticed this with dd1, who at eighteen has gone back to thinking she's the centre of the universe,a nd has been very challenging. She left home on Monday and whilst I will miss her, I can't say I'm sorry she moved out (with some strong encouragement from us to do so LOL).

Lulu, I'm sorry you're struggling. I'm always up for a PM
