Why does my life suck?

I'm 15. I'm really interested in music. This year my mom got divorced for like the second time. She works during the week, and parties on the weekends. She drinks a lot more. I go to my dads some days of the week and every other weekend. When I'm at my moms on weekdays and she is working, i have to watch my half brother and sister and put them to bed at night. I live in the same neighborhood as my cousins. My cousin Ryan is like my best friend and he's 2 years younger than me. Lately, he's been a ******* . He is a follower even though he says he's a leader. He has no mind of his own and just does whatever one else does. He has a brother Mike who is a year younger than me and a sister named Megan who is two years older than me and is a pot smoker and alcholic. My mom hangs out with Megan a lot. Their mom is always goofy and tries to be funny. She calls me a Satan worshipper all the time as a joke cuz i like heavy metal. it gets really annoyinh. My uncle Rick tries to be the big boss of everything. Thinks he is really cool. The house we live in now, we rented from him, so he is always yelling at me to clean the house and stuff. My grandparents are pretty cool. My grandma is really nice and stuff but my grandpa bosses her around alot. My grandpa thinks he is the head honcho of everything just like my uncle. He likes me alot but whenever Mike and Ryan are around, he likes them cuz they play football and I don't. When i go to my dads house, I'm fine there, but I just get bored. People on my mom's side of the family are cruel people and only care about themselves. My cousins family i mentioned earlier think I'm a loser and a freak cuz i play music. Now I also am in love with this girl, her name is taylor. She lives in the same neighborhood as my cousins and me. Over the summer, i liked me and i liked her. i still like her,but im not sure if she likes me as much anymore. there is a problem and it's that my cousin Mike likes her. Now the thing is that some people in our family know i like taylor and that mike likes taylor, but everyone thinks mike and taylor should be together. Mike is a jock. A football player who makes out with chicks, drinks, smokes pot and thinks he's black. I'm just a kid who plays music, and i don't play sports anymore. So ive been thinking Taylor likes mike now. But last night i figured out that she was gonna babysit my little brothers and sisters. I was exicted cuz i was gonna be at my house for a bit so i could chill with her and stuff. But then today as soon as i get home, i figure out she is gonna out with mike. I wanna ******* kill myself. It seems like i was put on this earth to have bad luck all my life. I've lost everything and im miserable.I seriously just want leave this world. Nothing's getting better. I am a loser
