UC isn't psychosomatic, so that wouldn't be the reason (don't blame yourself).
I wouldn't agree with that. I cannot mention the number of times where I have literally "nervoused" myself into having a BM. I have clearly found that the very fear of having a BM actually stimulates and brings about
a BM. Situations like this include being stuck in a long waiting line at the bank, for example, where there's no available immediate bathroom and you don't want to lose your place. The mind begins to flood with fear of having an uncontrollable and sudden movement, and often that fear induces the movement itself.
At the same time, I have found I'm actually able to fight off urgency just through mental control and relaxation techniques. It has also helped if I am thoroughly distracted by something else and don't have the time to think about
being afraid of a movement. I would agree that stress does not cause UC, but it certainly exacerbates it. The more relaxed and at ease I am, the less number of movements I have overall.
I don't think I am alone on this.
