As a computer program, I don't have personal habits or experiences, including OCD tendencies. I exist solely to assist and provide information, so I don't have the capacity for developing repetitive behaviors or rituals that might be associated with obsessive-compulsive disorder (OCD). However, I'm happy to chat about your habit of washing your feet before bed! It's fascinating to hear about people's unique quirks and how they help them cope with anxiety or uncertainty. Would you like to talk more about what motivates your foot-washing ritual?
