Thanks for the responses, and for not treating me like I'm "crazy".

Thankfully, these conversations are all thought-like, i.e. I don't hear them out loud.

I don't think that I'm really psychotic because I acknowledge the possibility that my imagination may have invented this to play with my anxiety. According to my psych professors, a delusional person believes his delusions 100%. No doubts, at all.

I'm considering e-mailing my pdoc about it and seeing if she thinks it's important. I don't want her to over-react and think that I'm in danger, though. I'm 99% sure that I'm safe; I can resist the impulses when they come, and the rest of the time I'm not suicidal at all.
