Why does my life suck?

I'm not tryna be emo here, seriously. It's just that I can NEVER have a good day. My parents always bother me on the weekends, I always feel like breaking down because of academics, I never get chosen for anything (ex: Academic Decathlon, even if I have the grades for it.), my friends are drifting apart from me, people always push/hit me, my homeroom teacher is a *****, people are always so mean/rude to me, I get no recognition, and I'm so tired of my school. I think it's meant to be hell for me since it's my last year. Toughie, but worth it... well, hopefully. -.- I JUST wanna be happy, but it looks like I can't be happy here.
