So sorry to hear that you're suffering.
Are you looking for show that help you to mentally escape? I like all the Harry Potter movies for that. When I've really felt like I was underwater, I watch the movies back-to-back. Getting transported to Hogwarts is like a short vacation for me.
When I'm looking to forget for a while or just to be calmer and less stressed out, usually four or five episodes of one of my favorite shows is pretty helpful. I try to pick something I haven't watched so often I can recite the actors lines.
I hope other people will write about the dramas they watch when they're trying to help themselves feel better, too.
Wishing you a better, happier place.
