Hair!!!

[Lindsey]

Okay there's a few posts here about haircuts, and I'm gonna add one more! I have long hair right now, and I was thinking of maybe cutting it. I had long hair my whole life until I moved away from home after high school and I chopped it all off! Some people liked it, some people didn't. I've went through a couple different styles since then, and now I don't know what to do. It's taken me two years to grow it out so I'm scared if I get it cut I'll hate it and miss my hair! It's funny I never really had that thought the first time I chopped it off!
My friends from back home have all moved to much bigger cities and have exciting lives and they all look SO DIFFERENT and grown up! I'm jealous! I love my hair long but I feel that it might make me look too young and I think I want a change.
Anyways, I'm here to ask advice... how should I cut my hair?

First pic is from May of this year (on the right), second is from a few years ago when I cut it really short (on the left), and it was just growing out. The last pic is me last week Hair's in a high ponytail but you can see how long it is even when it's up... right now it's almost to the backs of my elbows, and layered starting at about my shoulders.
