Something that has been eating away at my insides for a while and I need advice.

Im a VERY OCD person. I expect the best from myself and others. Ive been homeschooled most my life, and the time has finally come to leave. Im turning 18 on the 30th and graduating in May. I live in a isolated, desolate area full of what seems like inbred hill billies that live wit their parents. im constantly told im on the path to becoming one of these people. Ive been told im bright, smart, "gunna be just fine", even genius. My latest project has been sending a weather balloon to the edge of space and flying a RC plane down. (just one of my ambitious projects I cant focus on due to my emotions) My problem is I suck at math. bad. I can add, subtract, the basics.. run a calculator, all the basics. I learn by hands on, not math. and my Grammar is okay, but punctuation needs work. I was contacted by a Votech directly offering to explore their aviation school and let me fly some of their planes. I want to go for aircraft maintainence and possibly welding as a fallback. im still exploring. Im however worried my lack of skills in the social world and being a dumbass with school will land me in the mcdonalds. I am a person full of ambition and I never give up.. I have the want to succeed but I don't think i am academically capable. i have a skillset in certain places but i know that's almost worthless in todays society.

Please Help me and give me a glance of what the real world is like.. maybe im just too hard on myself
