I Haven't Known Where To Go For A While Now

I don't know where the past few years have gone.
I don't feel like I have done anything significant since finishing high school.
I don't know what to do or where to go.
And I feel like the longer i wait the more I'm going to lose until i realize I've lived my whole life doing nothing, and anything and everything i ever wanted to accomplish as a kid being left un-fulfilled. Its like no one can understand how i feel even when i try to explain it the best i can, but i know that is no ones fault, its something to do with the human condition. I just wish someone else could help me, but i know you can only help yourself. That's the part I'm having difficulty with, my-fucking-self.
Standing on the brink, my toes inching over the edge.
