I've always been able to fall asleep relatively quickly, so I can't say I know how it feels, but a compromise that may work are books.
Books on electronic devices don't count, e-ink like a kindle is fine, e-ink with android is not.
Bonus points if the book is a somewhat dry subject, no fiction novel or fantasy, but either something non-fiction (I read a lot of engineering or science related shit in bed) or if that's not your world then I found many historical books to be a good slow burn. The point is for it to be engaging enough so that your anxiety stays in check, but not so engaging you want to read it in one go like a good fiction book might be.
I didn't want to write out the stuff that comes to mind, so here's a picture of some of the books I physically own.
The blackened out ones would give away too much personal information, so I had to censor those.
Other than that, green is what I'd say perfectly fits the described nieche.
Orange might or might not depending on how easily you get sucked into those books. They are oten fiction but slower burns.
Red is a no-go as those are too engaging.
Some titles are german because I'm german, so for most historical works that weren't written in english to begin with I just buy whatever is cheaper, sorry for that.

A book that I don't physically own but is decent to read, especially in the context of /fat/ is "atomic habits" too.
But more than that, a lot of these are domain specific or books that interest ME or I feel like would benefit me. Best if you look for stuff that YOU want to read, these should just give you a rough feeling for the type I am talking about.
