Leaving society to live in the mountains

For the last few years I've quietly tolerated a horrendous job in retail in my home town of Cardiff ( Wales) aswell as a toxic group of fake friends. In my job I've been berated, spat at, told I'm dumb and ugly, laughed at, threatened, treated like a dog. And by my so called friends, I was abandoned at the lowest point of my life, I got within inches of suicide and I reached out to them all. Not a single call back, no messages returned, everyone ghosted me. About 3 years ago I made the decision to quietly start saving 80% of my salary and slowly start to close down and sever all ties to society and modern civilization. To this day, I haven't told a soul. I now have enough money saved and am currently buying about 30 acres of land in a remote area of the Welsh mountains I've been studying for about a year. It's remote enough that it's obscure and not on the tourist path, you can't find much information about the area online, there are no airbnb's no bed and breakfasts and It's only accessible by foot for the last hour of the journey across rough terrain. In other words it's where a guy goes when he wants to fall of the map. The land comes with permission to build a one bedroom cabin so long as the main income of the occupier is derived from the land ( known as an agricultural tie in the UK ). Which is fine considering I plan to go mostly self sufficient. I've been carefully severing all ties with civilization in the run up without anybody in my cirle knowing about it. I'm quitting my job, closed down my bank accounts, cancelled all subscriptions and mail. I've closed down all social media and requested that my name be removed from the electoral register ( public records of address in the UK ). I've cancelled my membership of my doctors practice, My dentist and have tied up all other lose ends. I plan to secretly visit the land for periods of a few days each month while I'm building the cabin I've carefully designed from DIY videos and forums. It will be humble and basic but comfortable, with one bedroom, one bathroom a small kitchen, a small lounge and a porch area, aswell as a tool shed outside. There will be running water from a storage tank for taps, showers etc and a distiller for converting it into drinking and cooking water. There will be solar generated electricity, with a diesel generater backup. The toilet tank will be fed by the run off from showers and sinks and will be neutralised by chemicals which I'll have to buy in bulk once per year. There will be satellite Internet for when i need to learn things but I'm intentionally taking an old dell computer with no access to social media. It will be just enough to access the Internet to learn what I need to learn. I'll also have a satellite phone for emergencies only. Other than that I plan to have no contact with the outside world. As for food and income to buy the necessities I can't make myself, I plan to raise animals and plant a variety of intensive crops. I'll also carry a minimum of one years dried food at any given time and harvest my own drinking water for food security incase the farming is insufficientt. Once I have set up, I plan to simply leave one day not telling abnybody anything about where I'm going or why I'm going there ( All the family who truly cared for me are no longer with us). I'll tell the authorities I'm moving out of the area but not to where incase on the of chance anybody cares enough to call the police and report me missing. That way the police will know I'm not missing and won't be able to open a case and come looking for me. I won't be voting or watching the news. I won't have a bank accountt and will conduct my affairs in cash only. I'll be putting up a low cost fence around my property and I plan on no human contact other than exchanging pleasantries with anybody I happen to cross paths with while walking out in the forests and mountains, taking the nature in. My nearest neighbour is about a mile away so this will be rare. I'm a few months away from this and I can't wait to just leave and be in my favorite place ( in nature ). I've already been there twice and I felt true freedom standing amongst the ancient valleys and mountains, not a soul around, the sounds of wildlife abundant and the fresh country air blowing through my hair. Only a few months until I check out of this decedant society for good. Wish me luck
