I don't know what to do with my life.?

I'm about to be a sophomore in high school and yes that is plenty of time to think of what to do after high school.. but i'm so lost. ALL jobs i've heard of, all majors in college i've heard of bore me to death. I don't want to be an adult & help people, I don't want to cook for people, clean for people, I dont want to build homes, do experiments, do surgeries on people, I don't want to work with pets, nor work with children ( I do volunteer work with them right now and its miserable), I don't want to help injured people, or work with medicine. Everything seems so dull & it seems like i'd be living in a life I don't want to. The only thing i've ever wanted to do was become a proffessional wrestler in the WWE, and right now my chances are slim.. i'm very skinny, barely 5"4, 111 lbs, I'm VERY shy.. I get so nervous talking to people to a point where my head and body and hands start to twitch & I get uncomfortable and act like I have a headache to avoid a conversation. I don't really have friends anymore, I just sit on the computer all day long until the next day arrives except when I have to do volunteer work. Anyways, i've also been interested in MTV Real World/ Road Rules challenges(Not really a job but cast members go on yearly to compete for cash prizes). As you can see, I only like phsyical things where I have to stay in physical shape where VERY few people are selected for out of the thousands that apply.. and my chances are SO slim in the only 2 things i'm interested in. But being wrestler has been my goal but if I can't do that I don't know what i'd do.. Is there any body out there like this? Any suggestions? :\
