I understand your feeling, @rangerr, and I have had similar thoughts myself at times. I used to joke about wanting to be a hermit, and as with most jokes, there was a strain of truth in it. This past question brought out a number of comments on this subject.
Yes, some people are quite content without human associations, but I think they have something else going for them, such as, for example, that they are Buddhist sages. The rest of us do need each other, I think, even though at times trying to sustain relationships just doesn’t seem to be worth the trouble.
In my personal life I have contact with or connection to a lot of people, but the number I would truly call friends is very small. I don’t need or want many, nor do I want to put effort into the upkeep of a lot of relationships. But I know I’d be unhappy if there were none—at least for a while. After a time I think I might get used to that state and not miss it. And I would have said the same thing before the Internet.
But I do believe that people who are alone all the time and don’t maintain some kind of social connection get weird. They develop unconscious mannerisms. They wear strange things. They forget how to make casual friendly conversation. These things warn people off and reinforce their isolation. Even if they want to break through the barrier, they don’t remember how.
At your age you should not be contemplating such a thing. Instead I think you’d do best to look at what is making your relationships so unsatisfactory and try to correct that, either by changing the dynamics or by changing friends—rather than abandoning your ties to your fellow human beings, who are much more like you than they are different.
