“its dark.. and hell is hot
Nice Hamlet quote.
I love Shakespeare.
As far as the sleeping problem goes, I appears that you're over-analyzing yourself. Do you have a tendency to do that? Being acutely aware of the workings of your mind can be a negative thing. I know I sometimes have that problem, and it prevents me from sleeping a lot. The best advice I can give is to stop thinking so much about it and to try to preoccupy yourself with other, safer, less consequential thoughts. :)
Hope things get better for you soon.
