Why does my friend make comments about my body?

Evidently she is a person who has to have the last say about someone. She's either "cutting them up" to make herself better, or saying something detrimental about someone. I wouldn't even "allow" someone of that nature to bother me tho. I'm sure everyone know just what she's like & no doubt takes what she says with a grain of salt! And, actually she is the one who is insecure about herself or she wouldn't have to say a word about anyone else. She's just showing how insecure she is about herself & has a bit of a low self esteem about herself too. Don't let it bother you, honey, it's on her not you. As I said, everyone must know the kind of person she is by now & they don't even pay any attention to her anyway. So don't you either. Of course she's not going to say anything to you about any of this as it would only make her look like a fool! Just ignore her & her stupid remarks they aren't worth you even getting upset over. And if course you're kinda use to it by now anyway, rite?! She's as transparent as a pain of gl & I'm sure everyone knows it by now too! They'd no doubt even be surprise if she didn't have a detrimental remark to say about others! Just let it go & ignore it just as I'm sure everyone else does. OR, you could ask her why does she make remarks about you after you've walked out of a room instead of saying them to you to your face instead, Whatever you feel more comfortable doing/saying,*
