[ Mental Health ] Open Question : Why is everything bad happening to me?

My dad is being an @sshole, he always makes me feel like a worthless piece of junk everytime I'm around him. I need to get money so I can buy my big brother something amazing for his birthday, since he always buys me expensive things. I Asked my favourite teacher if I could babysit his daughter, but he said he doesn't usually let his students babysit for him. but he did say he'd keep me in mind (this actually crushed me. I'm not an assertive person, and when I finally got the guts to ask, he said no) All my friends are leaving for Easter break, and I'm stuck at home, with no one to talk to, no one to hang out with (as usual.) I've had mono for 2 months so far. I wanted to be on the badminton team, soccer team, and football team. But I'm not allowed to do anything. I didn't even get to play badminton in gym class. I love to play sports. But I can't. Now this total self centered @ss keeps bragging that shes on the badminton, U16 soccer team (because he daddy's the coach), and on the football team. Ever since I've gotten mono, I can't play my trumpet the same. I have a talent in music that I was born with, but now I can barely play the trumpet. I also have the talent of art, but now I can't draw the same as I did and I keep messing up. So Many things are going wrong right now and i don't know why I'm so upset, but all I want to do is burst out and cry. These things may not seem like much, but they're extremely important to me. Mono is ruining my life. I got it because my "friend" didn't tell me she had it a month back and I drank the rest of her pop. How do I stop being so depressed. Right now I'm basically forcing myself not to cut again.
