Why I'm crazy

Yeah weird title I know. I wanted to illustrate a point though. Believe it or not some people do and I don't blame them for thinking that yeah I'm different but that's no reason to judge me. My parents are the main ones who don't get it, they think I'm a retarded guy that no one cares about an embarrassment to mankind. Especially my Dad he thinks every guy should be able to take a car apart and put it back together; which there's nothing wrong with that I admire people that can do that it's a good thing to know and I know how to do the basics change the oil rotate the tires stuff like that, but Dad thinks I should know it all. Then when I ask for some help with something that I don't understand he goes off on how I should know this stuff, like this evening I asked for some help with my Chevelle I figured we could spend some father-son time together working on the car but when I asked him he said no he didn't have time the couch was calling him. That really hurts me then I said just show me how to do this one thing and I'd let him go he went off on how I should already know how to do that. My friends know that I'm sane I just learn different than most folks. It's like my mind is always on always running away and I can't find the brakes. I do my best work when I've already been up for hours and hours right now I'm writing this on just 1 hour of sleep in the past 48 hours. Why can't he just understand and accept me. He's the only one that has this opinion my cuz says I'm the one that will take our family name somewhere, my youth pastor says I could work for Bill Gates, and my mom thinks I can do anything (I love my Mom LOL). Does anyone know why? Why can life be so cruel? Why was I born to this family. Why do I even exist? Just to fill up space? Just to make Carbon-dioxide for plants? I'm tired of living a life that has no meaning I want to go somewhere and break out of my shell I want to tear down these walls and climb over and see what's on the other side.
