It's easy to get the wrong impression online, so please have patience with me if I'm way off base, but it seems to me like you're potentially putting yourself in a lot of danger. 1. You have little to no experience with this type of trip 2. You're traveling with an enormous weight, setting yourself up for exhaustion and injury 3. You're traveling solo 4. you're using an unmaintained route. I know at a certain age, anything seems possible and you feel invincible, but the potential for not coming back from this trip is very real. You've gotten some great advice from some very experienced members here. Please please for your own sake listen to them.
