Trouble relaxing and sleeping

I have trouble about relaxing... I have no idea how to relax, what to do and stuff like that... And every day EVERY DAMN DAY SOMEONE IS ALWAYS BEING DAMN LOUD! EVERY DAY AT NIGHT SOMEONE RATHER TURNING IN MUSIC OR TALKING VERY LOUDLY OR LAUGHING LIKE A JAKAL!!! I'M SO DAMN TIRED OF THIS, I CAN'T SLEEP BECAUSE OF IT AMD U GO TO SLEEP AT 12 AM OR MORE AMD I'M SO DAMN TIRED!!!! I CAN'T SCREM AT THISE PEOPLE BECAUSE I'M SCARED THAT SOMEONE WILL SHUT ME UP OR THE PEOPLE WHO ARE BEING LOUD WILL SHUT ME UP OR DO SOMETHING BAD TO ME... I CAN'T RELAX! IT'S SO DAMN HARD BECAUSE OF THEM... And it's hard because I'm in stress after getting rid of maladaptive daydreaming and I don't know what to do with it... How to relax? What should I do? I noticed that i find something with dark theme really relaxing (not when there are something cruel or something like that, no, something like Tim Burton style, like, melancholic but at the same time deep, funny, positive but peaceful, calm and as i said deep) but i don't know... It's not helping actually but i like this kind of theme, i like it since my childhood and i consider myself as a goth so, yeah. I love goth music but I can't find any right now because if this stress, butni listened to it once in the last amd i liked it, so, i will continue to do it and that's why i consider myself as a goth. So, yeah... I think i find those dark themes relaxing but not helping because i like them, but they are nit helping me relax, it's just... I just like them, i find them really soothing and i feel safe, but in this situation they are nit helping me. When I'm in calm state, they are really relaxing, but when I'm in stress, they are relaxing but not helpful... But maybe they might help because I didn't even try but still, i think i need something other then this... But i don't know what...
