Has anyone once been overweight, lost the weight, and now there "friends" are jealous?

definitely drop them. they have no reason to be upset if all you're doing is caring for yourself and trying to be healthy. what you did is good. dont worry about what they think. girls are always going to be jealous whether we like it or not. they need to get over themselves and just be happy for you because thats what friends are supposed to do in this type of situation.
