Where does all the time go?

it's a vicious cycle, I try not to think about it, it hits quick like a rifle, well, how did I get here?! I swear it was just yesterday, I graduated highschool, but to my dismay, I woke up, and now I'm 26. I know that doesn't sound like a lot, but I just let the time pass, didn't savor it. rather, regretted it. it's a subject that makes me nervous, I don't want to look under the surface, I'm too afraid to see what I've missed.
