How can I help a friend who may be developing an intake disorder?

I have be best friends with this girl since I be 8 years old and am very soon 20. She is literally one of the prettiest people I know. She have a perfect amount but does not see herself that way. She have always thought her legs be too big. She is 5'4" and could weigh no more than 120 lbs.

We were spending time together ending night and she asked me if I required to start going to the gym with her and I told her I'd love to and it would be fun. She said she have gained substance and wanted to lose some. This, I thought may be ordinary. Then she told me that she had thrown up a few times after ingestion too much. She tried to down play it by saying that she have only done it a couple times and simply when she had eat way too much but I know better. I explained to her that this is how these things start out, as 'only just a couple times when I ate too much' but then it progresses to where on earth you are addicted to purging and can't stop.

She needs professional comfort which she may tell you that you are wrong. If at hand is a personal trainer or nutritionist at the gym you are considering or find a gym that has these services available, own them discuss this with her.
