I get thoughts like that, too. A while back, when I broke my hand, I used to get unpleasant thoughts with that. I obsessed over clenching my first, moving my hand, or taking the cast off, and in the end, the stress that entailed, caused me to twitch my hand/arm so much, that the broken bone slipped out of the place the surgeon put it in, and then it healed badly; I now get sometimes quite a bit of pain, a fair bit of discomfort, and limited movement, from it. Nun ja. I hope your "moment" (as I call them) passes, soon. I believe, I do feel your pain, figuratively speaking.
