You need to see your doctor soon. No medication can be prescribed without exam specially in this forum.

You have reached an educational site where health-related questions are addressed, but here, we do not diagnose, treat, prescribe, manage, or refer. However, a thorough virtual consultation here on HT could evaluate fully, and provide assistance. (www.connect@healthtap.com)

I believe that you're concerned about mild,at this time, obsessive compulsive mannerisms and activity. . A mental health professional can evaluate, advise and treat you with cognitive type therapy ( if deemed advisable). Your physician can refer you.
