Not starting the day off well

I have a feeling today is not going to be a good day. I've been having terrible nightmares the past month an a half or so, and I was having flashbacks all morning yesterday, so I decided not to go to sleep last night since I was terrified of having more nightmares. I ended up falling asleep, but only for about an hour. So now I'm exhausted, barely aware of my surroundings, and really anxious.
