Wash hands many time. Wash hands.

This could be due to obsessive compulsive disorder where you get compulsive habit to wash your hands several times after touching something that you assume might be dirty. Consult a doctor first as your doctor may do a physical examination  and bloodwork to make sure that your symptoms aren’t caused by something else. He/she will also talk with you about your feelings, thoughts, and habits. If your thoughts and habits keep you from doing what you want to do for at least an hour a day, you may have OCD. You might require treatment that  may be able to lessen how much your symptoms interfere with your life. Your doctor may prescribe medicine, send you to talk therapy, called psychotherapy, or both. First and foremost,  don't get worried or worked up as there are ways out to come out of it, provided you seek professional help.
