Hey Outlaw
People who are crazy dont worry about going crazy so cross that off your list.

I think that simple statement tells of volumes of despair, fustration and depression. You need to rest, your mind and body need a few hours off, to shut down and rest.
The feelings you were talking about are probably depersonalization and derealization, we all suffer from that occasionally when were are fatigued.
Do whatever you need to do to get some rest, even a few hours if possible.
Also try to give up the fight, let the anxiety come, let the panic come, let the depression come, but keep your mind occupied with something else. Even if its just a simple puzzle or music.
Hang in there it will get better but you have to make the changes.
