Tip for anyone dealing with this: it's not just a sleep hygiene thing. You're thinking about all those things because you didn't give yourself space to think about any of it during the day. Try to just sit without looking at your phone all the time. Try to have silence when you'd normally listen to music or a podcast.
Basically, try being bored again. You'll find your mind will fill in with these thoughts and you'll have an easier time processing them when you don't have the pressure of needing to sleep.
