I walk around and pace. I look for things to do, like check to make sure the oven is off, the refrigerator door is closed, the alarm is set, all the dresser drawers are closed, the doors are locked and other things. I check and recheck and recheck and recheck until it feels right and I am satisfied. I also do these things every morning and evening. Every time I do it I keep telling myself this is dumb, but I continue to do it. I definitely have OCD.
