I had this same dilemma when I was in 8th grade. A friend of mine was a hardcore bulemic. She used to tell me about it often and I was too afraid of making her angry by telling anyone that I just kept it to myself. Then one day she told me she was starting to vomit blood. It was at that point that I could no longer stay silent. I told a teacher that we both had that I trusted. She talked to my friend and later contacted my friend's mother. It took a while, and my friend was mad at me, but she got the help she needed and stopped hurting herself.

Sometimes, it's not easy being a good friend and you have to make choices that may end up hurting someone or ending the friendship, but better that than not taking any action.

Eating disorders KILL. Remember that.
