I'M NOT CRAZY! (Institutionalized!)

I assume that most people think I went crazy, because I changed for the worse so suddenly. I don't really think I'm crazy. Sure I say it a lot, and I'm afraid of becoming crazy, but I don't think I'm crazy now.. not yet anyways. All that happened was that I changed. Maybe for the worse at the time, but now I think it's for the better. I don't get caught up in petty things like what Brittney Spears ate for breakfast, or even what her latest single is (I hear them, yea, but I don't really care about them). I don't use drugs anymore. I'm not attracted to the bad kids anymore (granted I'm scared of everyone right now, but that's besides the point).
You know the kind of change I'm talking about, right? Not like, "I'm not goth anymore, I'm scene *pose*" but like, an Epiphany-esque change. A change that you feel with every fiber of your being. A change that means you'll never see the world the same again for as long as you'll live. I've had a bunch of these changes before, but they were usually subtle and slight. That night it literally hit me like a mac truck. On the highway. Speeding. I'm talking like a buck thirty in a sixty-five. So yea, it changed me. And it scared me, and it hurt. I mean, come on.. getting hit with heavy stuff really hard is scary, and it usually hurts.
So why doesn't anyone get it? Why do they act like I'm an alien? I'm still the same general person I was, I have the same sense of humor and stuff. I'm just nervous, that's all. I'm scared of people, so I'm really quiet at first. But then when I do speak everyone looks at me like I was speaking Japanese and said something really offensive about their dead grandparents. I just don't get it.
And no one feels like they need to clarify, or tell me what they think. They skirt around it, brush it off, they don't want to touch it with their bare hands. I mean, shit, I know I was a total bitch and a skanky ho, but JESUS so were every one of my friends at one point or another (okay, maybe not all of them, but some are definitely permanently stuck on bitch (I still loved them, though).). So how come when I went through a phase, it was like I pooped on their God or something. I KNOW my behavior was inexcusable, and I've told them that. I've tried to make it up, start anew, show them I'm sorry. But I guess I was just gone for too long and they got used to me not being around. And when I was around I was jumpy and happy and fucked up and loud, and then I come back and I'm meek, shyer than usual, quiet, and paranoid as fuck.

...I guess I understand why they think I'm crazy. But I'm not. I just had an abrupt realization about the people in this world and I was really shell shocked. And the fact that I had a little psychosis goin' on from drugs couldn't have made me look too good, either, I suppose
