How to find happiness in life again?

Ok, so I've been wondering lately, if this all life is suppose to be? It seems like all anyone does is finnish high school, go to collage, get married, have to kids and by a big house. I'm 18 and in my senior year of high school and I haven't enjoyed it one bit. High school seemed so slow, nothing but gossiping kids, fights, drugs, drinking, people cutting themselves, rumors, teachers not teaching(all they do is write notes on the board and have us copy it), its nothing but drama and my parents tell me since I haven't enjoyed high school, that Im going to regret it because life sucks after high school. They say its nothing but stress and drama. These things really been bothering me lately, I get so scared sometimes fearing that their is going to be nothing in life, but the things I mentioned. I originally want to be in the Army so I joined the DEP(delay entry program were you train with them one year before basic), but that's been like high school all over again, nothing but rumors and drama. My town is just a small town, with no place to go, just a grocery store, and house everywhere, nothing to do. I dont drink or smoke but 90% of the kids here do. I can't seem to find happiness anymore, no matter what I try it leads to more stress and drama. I skateboard but everywhere I skate, the cops get called or people get mad, I wanted to try BMX racing but I havent made it out to the track yet(rain, races cancelled,etc) I want to start a punk, metal or garage rock band but kids in my town only listen to mainstream rock, rap or emo. I really just want to find happiness again, but it seems I cant, how can I? Is life really just nothing but this?
