Yep. OCD runs in my family, and the expression was always being tossed around at home, even before it was trendy to do so.
Ever since I was grade-school age I can remember having all sorts of compulsory actions. Very particular things about organization, carefully coordinated physical movements and walking, checking (locks, appliances, etc.) and others.
I also have trichotillomania, which is an anxious compulsory pulling of hairs. This has caused me some appearance issues in the past, and is something I have an incredibly hard time keeping in check. If I don't watch myself, I will start doing it unconsciously.
And the current theory is that all this compulsion is the brain's attempt to combat nervous and obsessive thoughts... certainly true in my case.
