Ok, thanks for all your help and advice with 16 yr old daughter, both with aggression, temper and internet etc! For the second or third time found an empty bottle of cider in her room...was alerted cos she had a bottle opener on her drawers, when I asked her about it she said she'd won it in a cracker. (she lies VERY well) Her dad had tackled her about the fact she was on internet and phone in early hours a lot and I had calmed her down when she erupted over it. But again...lack of trust rears its ugly head. It's not that I strongly disapprove of her having alcohol, it's the fact she ' s drinking it alone in her room, and lying about it.
Am at the end of my tether, phoned a helpline and been in tears , just feel such a failure with her.
