hey brother i feel quite lonely too and im over 25. i don't think we can expect people to always be there for us or to understand that it is a human need to feel like part of the tribe. it's not people's fault, people are just different and can't help responding to the social environment the way they do... that is to say, sometimes it's not really our choice how we mesh with those beyond us. people are programmed differently- example-

i just did the Big Five Personality Test and I realize i may just have certain traits that isolate me, that i barely have any control over. it's like you said just getting "used to things" or like acceptance (maybe). however, getting used to things can also mean adjusting to diminished expectations of experience and that can be problematic--- "getting used to things" because perhaps it means we will be less dynamic, less responsive to the world, less responsive to ourselves and less primed to act and make decisions spontaneously.

(because we have accepted a certain position on how things are, we've subjected ourselves to a sort of determinism). anyway, although some people don't crowd around the comfort of the fire with their tribesmen, some of us exist along the borders of the collective social territory, and in the night of the soul perhaps we exist on that threshold so that we can be vigilant for those distracted by the flame or perhaps we are there to get our light from the stars. nothing is conclusive.
