Hi Drew, I’m in the UK too. Whereabouts in the country are you?
I’m much older than you and have had very different experiences, but as I see it the modern way of life is not really good for anybody. Some people do seem to like it and thrive, but many are not happy or healthy.
Have a look at diggersanddreamers website, and maybe selfsufficientish.com – there are others too, do a few searches. There are quite a lot of like-minded people out there. There’s the WWOOF organisation, where you can go and help on an organic farm for the weekend, in exchange for good food and a bed for the night.
Hope you can find what you’re looking for.
