Ugh, I know. I also have a bug phobia...it used to be a lot worse, but it's still pretty bad. Mine's not necessarily infestation related...I really just fear seeing bugs. The weird thing is, the things I fear most (roaches, crickets, grasshoppers) are the ones that really don't do any harm. Spiders I can deal with for some reason. I used to live in Florida, and the huge, flying Palmetto bugs (big, disgusting outdoor roaches) really freaked me out. I mean, I would completely freeze up if I even saw one. There would be no way I could even try to kill it.
Anyway, when my health anxiety starts to flare up though, I do also get a flare up of obsessive cleaning compulsions. I mean, don't get me wrong, I ordinarily clean more than a lot of people I know (my husband says I'm like "Monica" like on "Friends"), but when my HA is bad, the cleaning/sterilizing gets a lot worse. I will stay up and clean and sterilize the whole house...Lysol is my best friend. Part of it is I think fear of contaminating someone else, part of it is a fear of getting sicker if I'm exposed to germs. I do a lot of extra hand washing too. Since I tend to be most scared of contagious types of diseases (HIV, hepatitis, TB, etc.), I get super nervous if I sit next to someone who I think may be at risk for one of these things (regardless of the fact that I know rationally that I wouldn't be able to catch anything from simply sitting next to them. And it also doesn't make sense because I'll think I have a disease already but still get scared being in certain environments because I'll think that if I don't have it by chance, I'm definitely going to get it by being there). I think my type of HA may be somewhat OCD-related because of this.
All this said, I saw the bed bug thing on TV this morning too, and was really freaked out. It brought together the worst of my HA/bug phobia/contamination fears. I don't think someone could PAY me enough to sleep in a hotel right now...even a 5-star one because I would think that it would have bed bugs. And forget about going to the movies -- they said theaters were now infested with them. Truly disgusting.
