Hi, I read your query in detail and can understand your concern regarding your symptoms. From what you have mentioned, you seem to be suffering from anxiety disorder. It seems that you are having repetitive thoughts regarding the same and you understand such thoughts are irrational. Such thoughts can be termed as obsessions and the repeated cleaning or washing in response to the thoughts can be termed compulsions. Obsessive compulsive disorder is a type of anxiety disorder which is not uncommon. I would have liked to know about any other thoughts that might be coming repeatedly to you like any doubts (and repeated checking in response to that), repeated sexual or religious thoughts. I would suggest you seek a psychiatric consultation for detailed evaluation of your symptoms and starting proper treatment. Your condition can be treated effectively with medications like fluvoxamine or sertraline (one of the selective serotonin reuptake inhibitors). You will have to be patient about the response as the medicines will take at least 10-15 days to show its effect. The treatment will be long term and you will need regular follow-ups. Hope this information was helpful. Best wishes.
