Years back I would roll my eyes at guys who wore the full face shield for a little grinding, figured it was overkill and too hot to mess with. Then my buddy got a piece of metal in his eye and had to get it cut out just like you, and man did that change my tune fast. Now I keep a couple pairs of cheap wraparound glasses with the built in side plastic and they stay put way better than the clip on shields that flap around. The trick for fogging is the ones with those little vent slots on the sides, way less sweat than the sealed up kind. For a few bucks a pair you can buy several so there is always one within arm's reach, which honestly is the whole point after what you just went through.

Yes! The bathroom stall is my go-to too, something about that tiny locked space just lets your brain reset without anyone watching. I did the same thing last month after a rough meeting, gave myself 4 minutes then walked back out and fixed everything in half the time. Having a timer really helps because you know it has an end and you can stop the spiral.
