Quarter life crisis?

I am 24 years old. On June 30th I will turn 25, and this kind of terrifies me. 25?! How did that happen? It seems like I blinked somewhere in my teenage years and suddenly I'm supposed to be a grown up and do grown up things and just... Grow up! Am I supposed to settle down and start having children, or should I just go with the flow and see what happens? But if I do that, will I end up being too old by the time I decide I do want kids? Arghh! Such turmoil. Which got me wondering... Is there such a thing as a quarter life crisis?

I do realise that I am in fact still very young and a crisis over my age sounds extremely melodramatic at this stage but I do wonder if there is a kind of transition period between young and... not so young. Recently, I've found that I've "rediscovered" a lot of things from my youth - books, TV shows, etc and delving back into that world has felt strangely therapeutic, but also made me a little sad that those years are now behind me. On the other hand, I've also been thinking more and more about the "grown-up" side of life - having children, and a husband and all that. This also terrifies me. Even though I don't feel like I'm ready for "real" adult life to begin, I also don't feel like a teenager anymore - as much as I miss it, I have moved past that stage. So basically, I'm kind of stuck somewhere in the middle. Limbo.

I once read an article in which the author said she hated her twenties because she didn't feel settled and only really began to accept herself in her thirties. So maybe that's it - once I hit the big three-oh I'll feel pretty sweet. But that idea is way too scary right now. 30... years... old... Excuse me whilst I go breathe into a paper bag.
