Hey, I managed to read every word there
I just want to say that I understand the feeling of isolation on your part, although it was not due to the fact that I was extremely intelligent or anything of that particular nature, and I had a group of friends that I hung out with and they were a bad mix for me, I tried liking these people, but they really clashed with my personality. In fact, this particular group of "friends" had the habit of making me the butt of their jokes because I was so strange or that I seemed like I was drugs all the time. It wasn't the best feeling in the world, but I stuck with these friends because I thought I would be swallowed alive by the irrationally-judgmental environment that is High School (oh dear god, I hated High School). After high school, I washed myself clean of those people, and I couldn't be happier because of it.
But anyway, I'm in college now, and although I have not made a great deal of friends, but I have made a few. The great thing about college, especially community college, is that there is no real pressure to fit into some stupid social group and you don't have to fake who you are. I may be the guy with a wierd personality that isn't always inviting for social interaction, I be confident in the fact that although I won't have a lot a friends in my lifetime, I can begin to realize that the only opinions that really matter are the ones that lift me up.
Those negative opinions that others cast upon you do not mean jack-****. Those people don't know who you are, they only see what they want to see. They form negative thoughts about you, and they convince themselves that they are fact. Well, they are wrong!
The only authenticity that an idea has is the attention that you give it. The more you focus on someone's negative opinion, the more power you give it and it can begin to seem real. You shouldn't give those negative thoughts any credence, in fact, see through those falsified opinions for what they real are, baseless opinions. Overlook the negative, search for the positive influences around you instead.
You define who you are, not what someone else thinks about you.
