Feeling low about my confidence

I'm not a thin girl I'm on the thicker side. Yes I know that yes I look at myself everyday and yes sometimes I'm just completely not confident That I can't look at myself. I'm trying to love myself just the way I am and it's hard to be confident with my guy because of it. Just recently a was with my Bestfriend and  a guy asked did we go to the same college I said yes we are best friends and roommates and he goes and says "well how much did she pay you" I've never been so insulted in my life I really just wanted to curl up in a corner and cry. I just don't want to eat and lose weight so I can be accepted and feel better about myself 😔😪 . I want to be happy and loved and just feel whole again like I was use to .
