I'm at the top of a panic right now, so not sure if I can be great at talking you down, but I will offer this: I keep peeing too. And this just started suddenly.
I think when we panic, we pee. I experienced it once before and had to talk myself down by recognizing that pee symptoms caused by c-word don't just start up one day.
So if nothing else, know that peeing is totally an anxiety thing.
