The same trip was intense in terms of travel, so it was in part to help me find my mental and physical limits. I did find them, luckily I can still draw on adrenaline to get through a day or two and then, then the health crash. It’s not pretty when it happens. I go absolutely silent, all noises are magnified and it feels a lot like an anxiety attack and possibly appears that way too. It’s purely a physiological reaction, sort of the side effects of what happens in such an attack (so yes, you do go through some major physical chaanges as your body uses up energy stores and hormonal cascades burn up other. The major difference is the adrenaline making a heart race has long gone.
But it was very helpful and I did see a lot of beautiful spaces and actually see some of my own country again
