Is there anyone else that worries that they might get AIDS even when logically they know that they cannot? I used to worry about that a lot a couple of years ago. Like for example if I was at a party and had to use a public WC, I would start thinking that I might get AIDS or another terrible illness, or if somebody that I didn't know well drank from my bottle of water, or if I touched something dirty. Is that health anxiety, or OCD, or?
