Maybe I have a mild case of OCD, but I don't have a DX.
I have an obsession for sorting everything (alphabetically and chronologically), although sometimes my bedroom is a mess. Some years ago I made "the choco-flan day", we had to make choco-flan every friday, if my mom said "NO", I got angry.
I don't have an obsession with cleaning, and sometimes I pass days without taking a bath because I forget it or I think I have more important things to do
My mom says that when I was younger than 5, she took me with her outside, and we have to pass for the same places everyday in the car, if she took a diferent route, I cried and had a tantrum, then she had to return and take the correct route.
When I was a baby I didn't sleep at night until my mom took me with her to her car, and drove some minutes.
