Possible OCD: You are showing symptoms of Obsessive Compulsive Disorder. Everyone has a touch of it, especially under stress, or you may have a true case of it. Please see a clinical psychologist or another mental health pro who specializes in it. "The Boy Who Couldn't Stop Washing" by Rappaport is an oldie book about it. Peace and good health.

Anxiety: IT would be worth a good face to face evaluation, PCP is a good place to begin. There are medical issues that can cause things like this but definitely worth considering treatment which can be very helpful . Counseling is a good place to start, PCP shoul dhave some referral options .
