It sounds and looks risky, from what I have seen in the videos, but it is what you are passionate about and what you have in mind to do, and you have a focused goal, so you will achieve it and enjoy the experience to the fullest. The bad thing is to be alone in those places, not with a big group that can support you in certain situations. You have to prepare yourself very well and I'm sure you will. I am worried about... dangerous animals, the most dangerous ones, for example a snake bite in those far away places, what to do in that case.
It can be risky but the planning helps mitigate that which is why it all has to be planned out so well.
As for snakes, yeah I'm not a fan of snakes; they give me the bloody creeps. But, I've lived with th m my whole life (I'm from the country, not a city) and know how to minimise that particular threat. I also have the right emergency equipment which I've written about here and there.
If you never hear from me again after I leave for my trip you'll know I fucken died. 🥴
Oh my God, don't even say that as a joke! You'll come back safe and sound and with more experience, that's what I'm going to think.
