Sometimes accepting my flashbacks when I lie down to sleep is my solution. I let them play out, I experience the pain, confusion, fear, etc. and I promise myself that I will do something nice if I have nightmares that wake me up, but that I'm going to get some sleep in the meantime. It's like lying down to sleep in a burning building, but I do it anyway, and it helps.

I also sometimes find a playlist of sleeping songs to help, lullabyes, soft rock, just my personal favorites, like this one: (Owl City, Fireflies)

Big hugs, I hope you feel better soon. I'm glad you recognize you have some coping skills, let that give you hope that you'll gain more and be able to sleep better soon.
