Struggling to Fall Asleep, Need Help!

I have a hard time falling asleep. Like my mind doesn't want to shut off but my body is exhausted. I've tried making my room as comfortable and most adequate for sleeping. I covered my window to where it's as black as it can be. I have lots of pillows and blankets. I've tried listening to rain sounds, ASMR, playthroughs, essential oils and lotions, yet I still can't fall asleep. Is there anything you would know that could help, I'm open to all suggestions.
