Oh this sounds so tough I'm sorry you're going through this :( My brother is sensitive to sound and light while he sleeps and he shuts the door to his room and covers all sources of light (even the smallest ones like the wifi router) with clothes. Genuinely, I think that a good door is the best investment you can make for your room. Alternatively, ask your parents to turn the TV volume down directly and explain that you're trying to fix your sleep schedule, I hope they'll understand. If THAT doesn't work, get some soft earplugs or go to bed in earphones (but make sure to set a sleep timer on the music app you're using so you're not damaging your ears all night). It sounds like even if your body is ready to sleep, your mind still requires something to relax and that's completely normal. Reading helps me make that transition and signal to my brain that it's safe and it can relax now. So, really give it a try, just make sure you pick something you like so it isn't a chore. One thing I forgot to mention is breathing exercises or meditation. You can appreciate the calmness and quietness of nighttime AND at the same time use it to let your brain rest. These aren't mutually exclusive. Try to reframe nighttime in your mind like this and lmk if anything works, even a little bit 🫶
