I also had to Google "which one's heat exhaustion and which one's heat stroke again?" and then treat myself for heat exhaustion.

I felt really fucking grim but I did get better within half an hour of sitting down where it was air conditioned, drinking yet more water, and sneakily taking off my binder (I just sat topless in the bathroom for a few minutes).
Doing better now, feeling kinda fragile. And my ankle hurts but that's to be expected.
negative physical health
@Satsuma and I had like two or three reasons to be exhausted anyway
I will be careful and I will rest as much as I can.
