I'm sorry you're going through this. I myself was made fun of last night because my binder doesn't get me completely flat. I was told I should join the police academy because I was wearing what looked like a bullet-proof vest under my shirt. Earlier in the evening, this person walked up to me grabbed my chest and asked me where my boobs were. I laughed and said "they're there", but now that I look back on it, it was pretty ->-bleeped-<-ed up. I used to get really upset about what this person would say to me regarding my chest. So much so that I actually stopped binding for a while, but now I just shrug my shoulders because I just don't give a ->-bleeped-<- anymore what people say. It's taken me a while to get here and I'm still not 100% out, so yeah....I'm not 100% there, but I'm getting there. I've realized I can't change what people think and say. Yeah, I need to speak up more and call people out on their bull->-bleeped-<- because it is a form of bullying. But at the end of the day, I can't change them. I can't change what they think/say about me. I can just do me.
I know that might be hard for you because you're in high school yet, but I found when I stop giving a ->-bleeped-<-, my life gets easier. Are you saying anything in response? Do they know how you feel?
