@Papergirl1968 mentioned there wasn't much here for us adopters whose ACs are now teens. I agree.
I now have 2 teens. Younger one struggles with big emotions but is getting better.
Elder 'adult' teen is busy trying to be 25 but with a thinking age of 15. Trying I think to create her own nuclear family. Instead she is succeeding with us struggling not to go nuclear at her. We might all be happier short term if she moved out, but it really isn't right for her yet and luckily she and her BF can't afford to.
It's been like this for 2 years. I'm worn out. I'm hoping she may see the light about BF and how she has been behaving this coming year.
