I'm just beginning to explore the possibility of my having OCD, too.

I just thought it was interesting that you used to have little races with yourself as a kid. I had that too.

When I went to the restroom, I had to hurry and wash my hands before the toilet stopped flushing. I don't know why, but I did. And I took it pretty seriously.

The checking and rechecking things sounds really familiar, as well as the thinking of ways you could die.

Since, I've just begun exploring OCD, I can't say really for sure whether these are definitely OCD traits, but I can say things like that are why I'm wondering about myself having it.
