If you want the life of an animal, go read up on texts related to going innawoods. Buy a minuscule plot of land and a camper to live in. Get a PAYG SIM card plan for the internet, a large power bank and fifty or so 5L bottles of water. Stop by a local library or restaurant once a month to charge all of your elecreal womanics, perhaps buy a ruck-sack of some kind as to not draw attention whilst charging everything at once? Fill up your water bottles at whatever well you can find, feel free to bathe in it also. If this isn't possible get the cheapest gym membership possible to do the same. If you've read your texts, you could try to rely on fishing, hunting and the like, but if not simply purchase cheap tinned foods and medical supplements like vitamins. Fund everything through occasional sporadic DoorDash jobs, if of course you haven't set a few thousand aside prior. Lord knows how long you'll be able to live like this hahaha, just some loose thoughts and ideas I've accumulated myself over the past few years of thinking in approximation to yourself. Not the wanting to be a pig part but the wanting to separate and rid oneself of modern follies and tethering hahaha. There's a lot of prerequisites to such a plan, you figure out how to go about it and how to fund it all.
