I want to defecate as soon as I go out, and I'm afraid I can't find the toilet when I go out. I don't think so when I stay at home. What's the disease?

This problem is not a problem, nor is it a disease. It should have something to do with the environment in which I grew up. When I was a child, I should be a very introverted person. When I grew up, I changed my environment or felt uncomfortable in the face of new things, so I went to the suburbs to see more flowers and trees, and hit wild things with a slingshot. After a few days, I didn't know how to heal myself. .
