Nervessss

So I'm meeting my boyfriends friends for the first time this weekend. I've had some issues with his friends (they've messaged me say rude things etc.) and I've most definitely confronted them about everything and so has my boyfriend. I'm just nervous to finally meet them because I feel as though it'll be awkward. Also I'm a curvier girl and they always talk about skinny girls being the hottest and what not.. I'm just feeling really anxious. Any advice on how to handle myself when I meet them?
