About a week ago I looked at her computer and saw she has been on eating disorder forums and when I asked her about it she just got mad at me for looking at her stuff and told me to back off. And i have been noticing that she has gotten a little thinner but I always see her eat most of the food I make her. I have no idea what to do as when I spoke to her therapist, he said she is probably just going through a phase but I don't believe it! Any tips on what to do since my daughter wont explain why she was on them? (Also for clarification she didn't post anything about her, just joined in on some "games" on the forum.)
