How does it affect you?
Give examples.

I think about food a lot and what I am going to eat and when.
I also am very finicky about washing my hands and being clean from germs.
Getting dressed is a very tedious job; I also want to make sure I'm wearing the right clothes for the day, i.e not too warm or too cool for the weather. Just right.
It bothers me when my day is not balanced perfectly.
