@Butrflynet,
I had a then friend who at 5'10" insisted on being under 105.
I didn't know about anorexia then, not the details, and she was a very smart woman. She was insistent that she wasn't anorexic - I knew enough to inquire - and she was witty, engaging, for years.
I happen to now not like her at all, but I also don't know if she is still alive, for me to somehow not like her.
