Right now seems like a good time to talk about this, because the beliefs are currently in full swing (yay!)
Decided to go to bed (because I have 6 hours until I have to wake up), but I'm convinced that something is going to kill me. Not helped by the sudden noise that came from somewhere in my room. Near panic attacks are not very helpful to having restful sleep.

Anyway, my opinion on what the beliefs are is swimging more towards obsessive thoughts. There are some compulsive-type things I do in response to the thoughts, but I'll have to talk about them tomorrow.
Hopefully I'm actually going to sleep this time.
