how he's afraid D12 was purging because she's lost weight(this is his paranoia),
Just a word of caution - are you SURE he's just paranoid?
When my beautiful daughter was twelve, she started to lose a little weight. I thought she was just at that stage where girls start to lose their "baby fat". After all, I had been 5'6" 120 lbs in high school, so when she went from 5'4" 135 to 120, didn't think anything about it. After all, she was in junior lifeguards running around, and she was eating perfectly normally.
What we didn't find out until a few months later- until her classmates, god bless them, ratted her out to the school nurse - was that she was bulimic. She'd hidden her shrinking frame under winter sweats - by that time she was down to 100 lbs, and she got down to 89 skeletal pounds at her worst. She'd eat a perfectly normal dinner with us, wait an hour, then take her shower (she claimed it was easier to shower at night since she shared the bathroom with her two brothers) - and vomit in the shower.
Don't underestimate the ability of eating disordered kids to hide it. And don't assume that just because your daughter has always had a nice normal body image and attitude towards weight and appearance (like mine did!) that they can't fall prey to that insidious disease.
My daughter is well today, but only after intensive therapy and the sheer good luck of finding it out relatively early. Please don't dismiss his concerns too quickly. It is a deadly disease.
