Anyone but me

I feel like i'm drifting away from my life. Like I'm drifting away from everything i wanted to be. It's like every one else is going exactly where they need to go, but I don't know where that place is or how to get there. Everyone else is becoming adults while I'm stuck being a kid who still can't figure out which way is up. I thought I knew who I wanted to be in life, what I wanted to achieve. So far all my plans have fallen to shit and I don't know how to turn it around. I have no vision in my life whatsoever. Everything I do is just because it seemed like a good idea at the time. I drift along not knowing where I'll end up. Someone asked me what I wanted to be when I grew up. This isn't her.
