You're never alone.
When I was 13, my parents split up. My dad had a girlfriend, a blonde bimbo whore that's ten years younger than him. My mom got depressed, and I had to take care of her. Everything from cooking her food, to reminding her to go to work. She finally snapped when my dad sold the house we'd all lived in, and she got mean. She told me that I was a lazy bitch, and demanded more from me. I was already doing more than I ever thought I'd be able to, and at this point I was only 13, in the 8th grade. I snapped. I stopped doing anything for her, whether she told me to or not. I went into a spiraling suicidal depression, and started cutting myself. When my mom found out that I was cutting, suicidal, smoking, and in general being a bad kid, she did exactly nothing. Without therapy or any medication, I had to decide for myself if life was worth living. It was tough, and I spent a lot of time crying or apathetic, but I managed to work through it.
I could go on and on about life with my dad, too, but I dislike him even more than my mom, and I don't really like thinking about him.
Believe me when I say that life gets better. You don't need your parents approval to be happy, and they don't have to be happy for you to be happy. Turn your music up and ignore them. Apply yourself to schoolwork, so that when you graduate, you can get out of there and go to college.
I hope that things get better for you. Even if the situation with your parents doesn't improve, remember that you have all these people that review your stories that love you without ever meeting you. Stay strong. You are the better person.
