I’m sorry you’re going through this 😔 one thing that would help me when I was super anxious and couldn’t sleep was putting on a “comfort” show. For me that was The Office lol Also there are some good walking/scenery videos on YouTube that would help me relax enough to at least rest, sometimes fall asleep. There’s a guy called Action Kid who walks around NYC and narrates as he goes a bit and a guy named Johnny Strides who walks around Toronto. Not sure if this helps, but it helped me a bit :)
