Why do we always make fun of each other?

As a fellow bullying victim, I really feel for you and I totally agree. I think they lack empathy mainly. And are rather selfish and probably quite stupid too. Keep your chin up kiddo. Work on building your strong points. I was chronically shy and not the best looking kid on the block. One day I decided I was in charge of my own happiness. So I started telling myself I was confident and smart and funny, over and over, every day. And although at first I didn't believe it, eventually I did and so did everyone else. I haven't looked back. I'm still sensitive and easily hurt but I try not to let other people have power over me. Just keep telling yourself they don't matter and even if you're not tall, you are awesome in lots of other ways.
