Completely agree with Flow4.
I take heart from the fact that my mumbling, grumbling, complaining DS (13) does say sorry when I 'call him' on his muttering rudeness. I'm hopeful that it bodes well for his future relationships.
IMO 'Get out of my life, but first...' is very useful. BUT one size doesn't fit all when it comes to teens. Some need firm boundaries, some need reassurance and confidence-boosting, some need consistent punishments/rewards....
My two are quiet, shy, not feisty, indie, politically aware but you can tell them nothing. It's very frustrating. But if you're doing your best most of the time, it'll probably be okay. Hopefully.
I felt terrible about my DD for the best part of a year. She had a not-great boyfriend whose mum was undermining me and she let things slide/didn't seem to care about anything much except this boy, despite us living in a nice suburb, going to a very good (state) school,having lovely friends from lovely families, being gifted at her hobby and quite bright and attractive. I felt I must have made a poor job of bringing her up as she was so influenced by this (negative, unpopular) boy and his (not-particularly-desirable) family, kept thinking I was making the 'wrong' decision, even worried what my friends would think of me letting her spend a lot of time with him UNTIL...... a chance conversation with the mum of a girl who's now at cambridge uni - a studious, attractive, talented, sensible, go-getting girl - who had been in a very similar situation to my DD when she was the same age. This mum - who appears, calm, intelligent, thoughtful, - downright calm, I tell you had been very worried about her DD too. After that, I felt so much better about the way I'd dealt with my DD during that time.
I've had times when I've felt that I'm not capable of coping with teens and times when I've been so furious with them I can't decide whether to turf them out on to the street or run away myself and see how they manage without me then eh, eh!
Oh no - it's definitely not just you!
Teenagers weren't even invented until the 1950s anyway.

Hope you have a good day OP and the other posters. We deserve it.
