Been having problems with DD for 3 years now but got worse the last 6 months. She doesn't do what I ask her to do, poor school results, bad attitude towards us pArents and told all her friends we are the worst parents and that she hates us very much. She has no idea how to handle money but spends pocket money in no time at all. She has a boyfriend who we do not really approve of but we are polite to him. Reasons for our arguments is mostly that we will not allow the boyfriend in her bedroom nor would we allow her to be out late till 3 a.m. when she was 14. Will any of you parents out there allow these?
Tried to impose discipline or consequences for her actions but she will just turn around and say no. I caught her lying one time and said she is grounded. She said no way, I am going out and you can't stop me. Aside from physically stopping her, I can't do much. She screams, swears and insults me quite a lot even when we are just talking about how to solve a problem. She self -harmed before and when she doesn't get what she wants, she threatens to self-harm or starve herself and says it is our fault if she does it.
Any advice as to how we can improve our relationship would be welcome. Read lots of messages saying it will get better as teenagers get older but I feel so stressed when we have our falling out.
