Thanks for sharing The Magic 1, and let me add what I can.
Life is hell. Literal hell. To enjoy yourself here takes work and perseverance and dedication, a lot more than most people seem to realize. It can, and WILL, always get worse, now and then. It's inevitable in Hell. So buck up little guy, it's gonna be all right, if YOU make it that way. Only then. I too love hanging out with friends, it is an important part of my lifestyle, but it is also possible to find enough peace inside that other people come to find they like you, because you like you, and it's all good. It's vague I know, but each person rides alone. Doesn't mean we shouldn't TRY though.
Oh and anything you think sucks about being a civilian, sucks MORE as a soldier. Seriously. Ask around. So you think it's your out, but it wont be what you think it is. Just fucking finish school, realize you'll never have such awesome access to young available females again, go to a fucking party, realize it only gets worse from here, but you can carve out your niche some day. It just takes all the shit I already said.
