I used to struggle with bedwetting as a child, up to about 9 or 10 years old. Then I suppose I "grew out of it." When I first started opening up to my T at age 20 about my childhood physical/emotional abuse, my alters started coming out and I got dx'd DID. I had a really sudden regression where a little alter came out a lot. I started wetting the bed again, just like I used to when the abuse was going on. My T told me that that is a pretty common symptom of people who have been childhood sexually abused, but I had not been CSA. But he said it was different for everyone. When talking to my T about it, he suggested the "release" of the urine, was just like a release of emotion, when you are vulnerable, or asleep. Your body is so tensed up during the day, that when you finally get rest, your body actually relaxes too much, allowing the accident to occur. I am 22 now, almost 23, and the bedwetting has really gone down in frequency as I have been dealing and healing from the abuse. These days, I only have an accident maybe every few months. My live-in boyfriend struggled with bedwetting in his childhood and early adulthood around my age, and he like never does it anymore, but he understands so he makes me feel better when it happens. He helped me pick out a waterproof mattress cover, to protect the mattress in case of an accident. I hope this has helped.
