Really, Jasper-
I have always admired you as a person from the growth and genuine humanity you've shown on these boards over the course of your time here. I remember you were Christian of some variety and grew up conservative; and I remember you had, as everyone does, a tumult with your belief system as you went through--and you're still going through--the vital years where we exit the mostly fun ones and start caring so deeply about the bigger questions. You are a sincere person who has actual empathy and wants to do good by the other travellers you talk to every day. That is a great quality and one I have only personally been able to keep some of the time. I am not an old body yet, nor am I at an age where most people who meet me would put great stock into what I call my wisdom; but I do know that there is value in people like you, and I am sure that as you continue to grow even more, you'll find the ability to interact with people meaningfully and find people with whom you can interact meaningfully.
I share your loneliness, though. I hope all of us find at least one person we can spend our lives with. I do not expect it for myself; I don't know if anyone could handle the firecracker and neurotic bastard I have become. There has been, in my days, an extreme amount of suffering and heartbreak. (Some people here like to diminish what others feel on the basis that there are starving children somewhere on another continent, but I have a right to say that my life has been absolutely tragic and know that if I had ever related all of the details to anybody that they would probably cry.)
I'm not sure if all of this is advice, or if it's even tangentially related to what your post was about because I've already kinda forgot where I started, but I want you to know that there is reason to expect you will come across people you can establish a bond with if you just keep going, study the world and keep your curiosity, and against all the slings and arrows that fortune chooses to grant you, let nothing hurt you enough that you forget who you are, nor let the world forget that you have something to give it.
