Who cares about the people at school?
I don't. Want to know why? We aren't going to see them in a few years and they are going to be out of our lives sooner than you think. Why put so much focus and attention into people who couldn't care less about you and vice versa? When people tease or just act like a bitc.h.. I just laugh because what they say doesn't define me as a person. What nice thing have they done for you?
Stop thinking about the people who don't think about you. Ignore them because in the end, it won't matter. Those people won't matter, the words won't matter, the hurt, the stress.. Nothing.
Try thinking of yourself and what matters to you because in school.. that's all that matters.
