What's wrong with me?

I feel miserable. I don't know why. It feels like my life is one giant drama movie. Im always worrying about things , Im sooooooo tired of nobody being on my team ( if you know what I mean ) , I feel like im always gonna get in trouble ( even when I know that I have done anything ) , I always feel like I dropped a secret note on the floor in my school hallway and some adult is gonna pick it up and read it , I always feel like people are out to get me and purposefully not laugh at my jokes , I always feel like I have the lowest grades in my cl and I always feel like everybody else is out having fun wih their friends enjoying life while im at home . What's wrong with me? Docters out there , psychology majors, whats my issue?
