I hiked across the Alps, alone, on foot and camping in the wild for 3 months. I had no phone with me (no GPS) and just paper maps, and a pen to keep notes on paper. It was the best time I ever had my whole life. I thought I might get lonely but being in the flow of walking every day actually created some kind of an internal dialogue in my head which never made me feel lonely. I met others who were on a similar trail…
I'm curious, did you bring a book?
edit: my rucksack had initially 17kg when I left home. for this type of thing it is much too heavy. But the reason I packed so much was because I thought I will not be covering such a large distance and instead hang out at great spots that I'd discover, build a shelter, make a fire, build traps, catch some fish etc. Once I was on the road I changed my mind because the actual walking was so fulfilling. So my initial list of items weren't needed. Next time I do it I will either stay in one place and bring a lot, or keep my weight below 8kg. One thing I never regretted is to use a proper 1-man ultralight tent (700g) instead of a tarp. The one person who I met who used a tarp was harassed by ants and bugs every night :D
