MissKitty,
Wow, what a wonderfully engaging post and thread, nice work.
I can relate to much of what you've said.
I have no idea if any of the following will be of use to you, but here's a few thoughts from my own experience.
WRITER: You sound like a writer to me. You've demonstrated an ability at it here, and writers are often observers much more than participants. Being a somewhat reclusive writer is obviously a different experience than being the life of the party around the water cooler, but it does provide an opportunity to communicate with far more people on a much deeper level than most real world conversations can often accomplish.
Some of us are born with both feet on the ground, fully immersed in the middle of the social experience.
Others of us are born a hundred feet off the ground, which can be a lonely experience sometimes, but that distance from the action can also provide a breathtaking perspective often not available to those on the ground.
And some of us are born in orbit around the planet, the great sages and the insane.
NATURE: I've spent years in nature by myself, and have learned something I find useful. We all need to bond and merge with something, but it doesn't always have to be other people. Our fellow humans are cool, but actually we're all pretty darn boring compared to the glorious wonder of the larger natural world. When I'm in the woods the mad hatter social rat race we humans can be so obsessed with just doesn't feel that important. Armadillos seem more interesting, and yes, I'm serious.
AGE: Social issues can be much more pressing, confusing and problematic in our teens and twenties, a time when the peer group can be a dictatorship of sorts. I don't know your age, but if you're young, just wait, and it will likely all matter far less before long.
Good luck, and keep writing!
