Just roll with it for now, anon. The great paradox of life is that young people are forced to decide their life's path, when they really don't know much about the world - or even themselves, yet.
I'm 38 with a dream job and a hot wife who still looks fantastic after two kids. My life could not be better and I wake up each morning excited to see what the day brings. But I will say I had nothing figured out until I was at least 33-34. The 20s and early 30s are shit. I was miserable and confused much of those years.
Just trust your instincts, give yourself time to figure out who you are. There's no rush. Just stay away from drugs and from long-term relationships for now. Develop yourself, whether that means school, or art, or travel. You'll get where you're supposed to be eventually, anon.
