I am VERY AWAKE, TOO AWAKE, SO AWAKE IT EXHAUSTS ME.

Well said! Well said! I am literally tired, but hyperalert all the time. I have to take Ambien to get any sleep AND I cannot share a room with a human if I want to get any sleep (and that includes my husband or a friend). I can only sleep in the same room with an animal. I hear every breath, every swallow.
I crave being alone. I get so tired of the noise and drama of other people.
