Yeah, I get this too ever since I've had UC. I'm still flaring...for me it's not just anxiety, but any heightened emotion. For example the other day I was watching something funny on TV and laughed really hard (which was nice because I've been depressed lately). Sure enough I had to make a run for it. :facepalm:
I can't sing too hard in the car anymore either
funny I have the opposite car/meeting anxiety - if I'm driving somewhere I get really anxious, but as soon as I arrive and have a restroom available it calms down.
