Moving to the Sierra Nevada mountains and living by myself in a car while I hike

I (20m) suffer from a few genetic conditions that make me quite frankly unattractive, this isn’t a post about how to get better looking or how to grow self confidence, been there done that and tbh I don’t care. I live in Arizona and used to go to trips to the Sierra Nevada mountain range to be in complete solitude and at peace away from civilization. I inherited 100k and have no living relatives apart from one uncle who lives across the USA and my father who abandoned me and my late mother when I was 13. I plain on living off of the 100k and using my car as a house until I can find a way to live off the land. I’m an avid hiker and outdoorsman and there’s parts of the mountain range which are very quiet and empty and I plan to be there. When I think about this future life I am no longer depressed about my life and how it’s gone and am actually excited about the future. I’m am quite happy
