What a completely redundant article. I don't see the purpose of it.
It contains nothing of any value about how to handle this sort of situation, no ideas on how to protect our children from these pressures, no thoughts on where these ideas may have come from (apart from some vague 'guilty mummy' stuff - what about school bullying/peer pressure etc.etc?).
I can't begin to think why this woman felt is was appropriate to write an article making her DD a target for gossip and bullying - it really doesn't matter whether it is true or not.
Oh, and why am I not surprised that the daughter has stopped writing down how she feels about herself? Doesn't mean that she has stopped feeling that way, just cos mummy can't read it in a diary (assuming it is true).
