I am sorry this is a struggle. Hand washing is of course important, but not to the point where you have raw chapped hands. The CDC recommends washing hands 20 to 30 seconds. A good rough estimate would be humming the Happy Birthday song twice through. The fact that you must wash your hands a certain number of times in a ritualistic fashion is indicative of OCD. This means the behavior tends toward becoming fixed in a narrow pattern with recognizable steps and repeated in order sequence. Your attempts to prevent germs can actually backfire. Over-washing can cause hands to dry out, crack and bleed, which allows germs to enter the body. So what to do about OCD? If you have the resources, I would encourage you to seek help from a licensed therapist. You can also seek help from your healthcare provider. Most importantly know that this is treatable and it does not have to control or ruin your life. OCD is manageable and you can take back control. I'm sending you positive thoughts and lots of well wishes.
