Yep, got some paranoia here too. Right now it's because my workplace just hired a new part-time nurse and I'm afraid she's going to be my replacement, even though there have been no indications that I'm in any danger. It's just that I'm very limited in what I can do as a nurse anymore, and I was let go from a management job earlier this year so I've become very jittery and nervous about work in general.

I also get paranoid during episodes of mania, mostly I think people are looking at me and making fun of me, or they want to spoil my fun.
