It upsets me so much when people are talking while I'm trying to go to sleep?

The walls in my house are so thin but when I shut the door in my room the noise goes down a little. I would keep my door shut at all times but I have a kitten who does stuff at night and will meow ,profusely if I close the door, locking him in or out. It's like my family has no respect for me or anyone else, and they'll talk loudly and play music at 12 AM and I literally can't fall asleep until there's silence. And then the next morning my mom will tell me that I need to go to sleep earlier. How the ****? I'm a junior and I wake up at 7 every morning to go to school and I just haven't been able to get a good nights sleep sadly and it's really frustrating. Sometimes I even curse at the person who's being loud and tell them to shut the up but they don't care.
