Hello, this cleanliness addiction is actually caused by your own understanding of cleanliness addiction, what's more, in the college era of collective life, it is impossible for you to have personal space, especially the existence of roommates. At this time, you need to lower your standards. You can manage yourself, but you can't ask others. If you insist on asking others, it may affect normal social interaction. I suggest that you can sincerely explain to your roommates some requirements about your life scope, indicating that you also want to change this cleanliness addiction, but you can't change it for the time being, so please forgive them. I believe as long as their lives are not affected, they should accept your request. Also, you can see a counselor.
