Ever feel like you don't belong here?

I mean I don't really understand it but when I look at life I feel like there is nothing to be cheerful about. And why people don't listen to the world and it's cry's of sadness. We live in a world of fear and the only thing people can focus on are their dame electronics. I have lost my faith in the human race and I'm only 16 years old, I havent even lived a full life yet. I see people at school and all they can focus on is having sex, at their age and already having sex. And when I see someone being mistreated I can't help but feel sorry for them and going to them and trying to cheer them up, when I had nothing to do with it. And people see that and they think you are having sex with them or something. I just read this one question where a girl at 14 was asking how to give a blowj*b. And people don't pay attention to what goes on over seas, wars are fought for land and resources they don't get what they are doing ravaging the world. I feel like an old hermit that is only the one seeing what is transpiring. Another guy with the same exact question as me made me want to ask questions and say how I feel. I feel like I am greater for something and I don't want to be a working man in this black and white world. The world just seems so meaningless to me and I can't help but feel sad for this world. I act like nothing bothers me and put on a smile for everyone around me so I don't bring everyone down but this sadness just keeps on getting to me.
