I'm so glad you came through this, Rohag, but it was hardly "unscathed,"--was it? You've been through the wars, my friend.
I can emphathize to a degree.It's the combination of heat and humidity that's really dangerous for me. It has been since I was a child here in Florida. My mother accused me of being lazy when I wouldn't work with her out in the yard, but when I tried I ended up in the hospital--sunstroke and dehydration in really just a few minutes! No tolerance, not even a little bit.
There's a mental factor too, because I feel like my body is just shutting down. The doctor even now doesn't really explain it--just tells me to avoid the heat.
Now the dry heat I can take a lot better than this with humidity. Dry heat, as long as I stay well hydrated, I can tolerate right well. Strange.
I hope with time you recover from most of the residual trauma.
