where would the best place be to go out in the woods and be self sufficient be?

im a highschool dropout autistic neet, in my mid twenties been depressed most my life and i know that i'll never be able to get a job and work with other people and cant work online because im no computer nerd. (and id still be depressed if i could anyways.) so i think being self sufficient out in the woods alone somewhere with no human contact just my dog for the rest of my life would let me be happy and give me a purpose. And not have to leech off the government. i cant work with other people
if i had to take survival training for a few years get /fit/ and buy alot of equipment that's fine but i dont know where/if this is even possible in todays world long term. (legally or somewhere id never be found.) would i have to buy land? how expensive is that? (i know it depends but generally) A place where i could hunt, fish(light fires, etc) and not freeze to death. where i would have no more need for money hopefully.
(i have a canadian and american passport but open to anywhere)
