I've said it once and I'll say it again: Teenagers (especially girls) are some of the meanest people on the planet. I didn't even like teenagers when I was one...
(Plus - who's to say that their '92'-lb bodies are any healthier than yours? Plus, they probably don't have any boobs anyway...lol - just kidding, people!)
*Most* (I say most because there are a few that pretty good people) are still trying to fit in and spend most of their energy doing it that they don't even know what they are doing because of their maturity level...(yes everyone - I do realize the I'm not behaving very maturely in this post)
Just keep in mind that you are an adult and what goes around comes around...sooner or later
But seriously - Great job on the 17-lb loss! You are doing a great job!
