I suppose I experience varying levels of paranoia always. I'm always generally suspicious of everyone(aside from the few people I am very close with. The rest of the world? I don't trust!) But there are definitely periods of time in which I become extra-paranoid. I worry in an extreme way about intruders and prowlers in the night, I suspect the guys working on the house across the street are plotting something against me or my house, I worry there are aliens stalking me in the shadows on my property, I have a vague, general paranoia that my communications are being monitored and even my movements tracked. It causes significant anxiety when it gets to that point, I worry about everything. I've been feeling paranoid lately, the other night a police car pulled someone over not far down my street. I was sitting in the house, in the dark, alone, and saw the flashing police lights light up my dining and kitchen area. I panicked, I was certain a SWAT team and/or the FBI was here for me. Why? I don't know, but I must've done something! I get that way when I'm hypomanic, when I'm depressed, and even when I'm feeling otherwise fine. So I can't say it's necessarily related to bipolar with me, though it is probably definitely aggravated by it.
