I feel totally out of my depth here and would really appreciate some advice. My Dd12 is 5'2" and weighs 5 stone. Some little punk at school is constantly being nasty to everyone. A few months ago he said the dd12 looked like a boy and that she was ugly. She is at that age where she is very self conscious and totally took it to heart (sobbed her heart out for days). He has know told her that she is fat and it's really affected her again. She has started weighing herself and been googling how to lose weight. I have told her that she is perfect the way that she is but she's having none of it, went on the NHS website to check her bmi and showed her that she was underweight but according to her they are liars. Got upset today as she was heavier than yesterday. I'm not wanting this to turn into a very unhealthy opinion of herself and would appreciate any advice anyone has. Xx
