Call me a cynic, but a fundamental aspect of SOME people's personalities is that they do not like seeing other people happy, or they are jealous of someone else's success. Some people may not want you to lose any more weight because they feel threatened by your improved appearance. Given your height and weight (similar to mine), you are at a healthy weight, and losing a few more if that is what you want to do would not make you too thin. I want to be 125 myself, but even losing another 15 lb. at my height would not, in my opinion, make me look too thin. You just have to smile at those people, say "Thank you, I take that as a compliment" and walk away.
