I am just 21, too young, but I really want to go to another world. :(

I don't feel happy with this world, I see so much ignorance, injustice, drama, fights. I also see people don't take me seriously, they prefer to be in their ignorant lives, full of TV, commercial music, fanatism, etc. I try to make them think about the world we are in, but they take me as a joke. I tell them about our nature, and they just say "Nothing won't happen!". Even I am not the kind girl every man want. I want to live alone and get a job, I don't want to get married, I don't want to be a mother. I think knowledge, art and job are more important than living with your partner, getting married, being a mother (sorry if I offended someone with this thought).
The only people I feel is taking me seriously are some Internet friends, but is not enough to me... I want friends like them in real life. I want to share knowledge, ideas, world views... That's impossible.
I want to spread all my knowledge in Internet, so people can learn to think by themselves. I want to help them with that. I want to open an Esperanto club in my city, for the moment, I am the only girl who is learning this language (my city is so small, you know). I want to give free classes and ask the government to put this language in schools because I consider it a good language, easy, funny, a good option to make it universal.
The sad thing is I also want to die, at the same time. Is like I want to grant all the things I wrote above and then search my own death, like this world is not my world. Like I don't belong here, like that Radiohead song says. I feel alone, so alone in this world, I feel like that 18 years old dude who was so smart and bullied in school, and then did a massacre. I don't want to kill people, hey, but I think I am going to end like him. Alone, dead, but could spread lots of knowledge around the world.
