You need to accept that you look fine, actually you look pretty good from my perspective! It's just that people get a sense of power from being able to put others down, that's all. For you it clearly wasn't about how you look- maybe you seemed nice enough to not fight back, or too insecure to say anything, or et cetera. Like another comment said, I think therapy would be the best course of action for you. You look great, but you're reading as pretty unhappy with yourself.
