For people that have a fear of wetting themselves before going to bed, I had the same obsession BUT! here’s how I fixed it: Before going to bed, I go to the bathroom. It’s a nightly routine thay most people follow, but that’s where the issue started. My OCD would tense me up so much, I couldn’t pee. So, I said to myself, “I’m going to pee by the count of 5. If I don’t, I’m going to bed and I’m not getting up.” So I counted 5, 4, 3, 2, 1… and if I did not start going to the bathroom by the end of my count, I said to my mind, “You didn’t let me pee, so I’m going to bed and will not get up.” Let me tell you, my mind was PISSED off and VERY anxious. But I didn’t get up and I didn’t give in. This obsession went away after a month.
