I usually check my closet doors, lights and locks several times over before I leave the house. It has often caused me to nearly be late for work. There are many times I recheck things without any need. I check my car several times, and I even go back after I hear the beep (to assure it's locked). My friend just sort of laughs at this. Are there other symptoms I should look for? I'm probably misdiagnosing myself.
