I should add that once in university I experienced something close to solitary confinement. Had to stay alone in a big empty house owner winter break. No tv. No books. A snow storm locked me inside. Almost all campus stores were gone, the main areas totally empty.
As others went home to their families I had no human interaction for about three weeks. During that whole time I received one call from family and friends, if you will call them that, which escalated feelings if being unloved, uncared for and worthless in the eyes of all who knew me or bothered to look or think in my direction.
It was VERY hard, Grangram, now that you mention it, and ultimately consequential as in my darkness and I redirected the remainder of my university experience in ways that were based on my perception then of complete and total estrangement.
However, this isolation I describe was imposed by circumstance, a very different thing than what this vid represents. My thinking as I write now, is that I would do such a thing again if only to revisit that episode from higher ground. Maybe I'm overestimating my capacities, but in looking back I see that one reason why this experience was so difficult: I had been using the campus scene to create the perception of closeness from others, without realizing this, because I had not had such feelings fulfilled prior to this time. That long lonely winter imposed abd fully exposed a truth that I had been trying push to the side for some time.
At this stage I would enter the picture knowing how few people would care about what I was about to do. They would be the only ones I would bother sharing my plans and subsequent lessons with, if only as a reminder of what I learned the first time around: that the vast majority of others really don't care about me, even to this day, whether I like that or not. I have no bitterness about this, just awareness and acceptance.
At this time, I would start such a quest with a much more seasoned awareness of God's love for me, personally, based on realizations that I experienced after university. It would be interesting to see if that would carry me through the loneliness, and what might come if going out time the desert for the sole purpose of stoking my relationship with God.
