If you want, I have a tiny amount of chapters for my story Blue Water. if you wanted to check that out ^^ It's an original, and it's about a model/singer getting revenge >:3
I have trouble getting to sleep as well, I've just sort of learned to deal with it and not think much of it. So I don't have any advice, sorry. Hopefully you find something that works for you though.
You can check out Kuchisake-onna or Kokkuri if you're interested. They're both original fiction horror one-shots.
I'm having the same problem with sleep, I'm trying to skip a night entirely in the hopes it'll tire me enough so I'll fall alseep at a normal time tomorrow night xD bad logic, I know.
Also, if you want to check out my story Doll, that'd be awesome :D it's a Batman fanfiction :)
