I discovered that it helps when I actually put in effort to fix my sleep schedule. Like getting off screen 1 hour before I sleep. Boxing bedtime to 23:00-08:00. And similar things.
It is just really difficult to fix for me but it doesn't feel impossible. I have made progress in last 6 months but trying different methods and only some portion of that progress stays permanent.
Also have the same experience fighting depression-like symptoms and anxiety. It just takes a lot of time and is difficult. Some people just don't have these problems and I do but this doesn't mean I am genetically attuned to be like this and I can't do anything. It is just difficult.
