That emotion...

First time I have actually felt so much emotion in months. It was a variety of anger. Not the normal upset angry. It was more like "just want to hunt down some jerks and kill them after making them beg for forgiveness." Luckily for them I am more than capable of restraining myself although I do believe I would be quite capable in doing the deed.
Why was I angry? well... I was persecuted because I am introverted. That was the only reason.

How about a few quotes from them:

"guys, please stop with the introvert persecution. now, as i was saying, as we can see from hazimoto oni oni: schoolgirl panty surprise episode 24, season 3, it is clear that introverts are treated in glorious nippon with the dignity and respect they truly deserve, unlike *ugh* uncontemplative americans"

"One would think a liberal arts college would welcome introverts, since scholarship is an introverted, rather solitary activity. I guess the educrats have determined that unless they make college resemble an episode of Sesame Street, the ADD-riddled brains of potential undergrads will go into gimbal lock. Hence orientation degenerates into Short Attention Span Theater."

I would be able to throw out a few more quotes, one of which stated that all introverts have aspergers and such, but I can no longer give quotes because those were reported as hate speech.

I really wanted to kill them in a way that would let them know who was making them suffer.... I am not even entirely clear in how to react to this blatant hate.

What? Who exactly was making all those comments? Fellow students? Administration?

Introversion is a normal way of reacting to the world. Introversion is not the same thing as shyness, but it is a personality factor which means the person is more energized, if you will, by spending some time alone, rather than with people. Extroverts are recharged by being with people, on the other hand. You might find Carl Jung's writings on the subject. I believe he was the one who came up with these terms.

Is there a counselor or someone else at your school you can talk to? I can understand your anger, but getting too enraged is not healthy. I am glad you have control. But I think you do need to tell someone in your environment about what is going on.
