I'm compulsively messy. I don't like people to know. It isn't as though anyone who comes to my apartment can't tell that I am a very messy person, but I don't admit why.
I also have a cleaning phobia. I know that it is irrational. I know that I should just work past it. But clean can send me into a mild panic (usually mild enough that I can keep working, but not always).
My husband doesn't clean much and isn't really around much, so the whole apartment is really messy. I try to make sure that all of my pets have clean cages/living spaces and enough food - but that is about the extent of my cleaning lately.
My grandmother and sister are compulsively clean. When my sister was over, for like 30 minutes, before my wedding, she started cleaning my apartment. I felt really embarrassed, because I knew she was judging me.
