Bad Night!

My sleep anxiety has been getting worse. I find myself dreading midnight- bedtime- more and more. It was so bad last night that I felt like I was having some kind of mini panic/anxiety episode. The only upside is that I eventually fell asleep in front of my computer for like an hour, then maybe got some more sleep after that.
I don't currently take any medications to help with sleep or anxiety. But if this persists, I hope my doctor will prescribe me something. I can't go to work and go through life feeling like my chest is going to explode.
