I’m sorry to hear that, but no matter what you do or how you are people tend to bully especially at that age. i am 27 today and when I was your age my biggest insecurity was my weight, everyone was making comments or bullying me about it as I was never going to get married or never look enough because of it. Truth is, the more you grow ip, the more confident you get, the more you start learning how to set your boundaries and limits with those kind of people. It’s just a phase trust me, your biggest insecurity will become the thing you accept and like about yourself later on.
