This is my first post, so be gentle. My 13 yr old dd has made our family life very difficult for well over a year. She shouts all the time, is aggressive and violent, swears at us (even her 8 year old brother). Her room is a complete pit - you can’t see the actual floor - but that’s the least of out problems. She’s been shielding because of a lung disorder (that can be managed, but not cured). She stayed in the house for about 10 weeks, but for the last 3 she has been going out, not socially distancing, going into shops, handling money, getting public transport. I’ve now seen 2 video clips where she’s vaping. We’ve tried everything- calmly talking, shouting, turning off WiFi, confiscating phone, using parental controls on phone. I really do not know what to do and it feels like it has ruined our relationship. Her younger sister is very anxious because of all the tension and arguments. She’s reaching out to meet up with people she doesn’t know that well. I’m really worried about the young person she’s becoming. If anyone has been through this and can offer me advice, I would be grateful.
