Trekking Trav,
Given your overall circumstances, I would urge you to take what money you have or are able to raise, and just go.
Ultimately, you don’t have to finish the “through-hike”, most don’t. But, you’re in a good spot, lifewise, to set off on a potentially fantastic adventure.
Just go and see how far you get, regardless of what you have in your pocket. However it turns out, no matter how far you get, whether you finish or not, you’ll be a winner, never regret it, and always be glad you did.
Now get going.
