Haircut dilemma!

I have a haircut appointment on Monday-no big deal, right? I was planning on getting the usual...an inch or so trimmed and a touch up on my all over dark brown color. Easy-peasy! Well, I've been wanting to grow my hair out for awhile now and it's getting sooooo long-- almost mid-back range! Woo- hoo for me! Buuuuut, and this is a big but (hehe), I have seen so many darling short haircuts lately that have been distracting my plans. I am now confused at the style I want. I thought I wanted long hair, but then again, my hair is so fine that it tends to look stringy when it grows out. But, I'm also afraid of losing all my hair and hating it when/if I decide to take the plunge and cut it--yikes! *Side note, Mom, I know if you're reading this you're on the verge of a heart attack so please take a sec to breathe ;-). * Here are some pics that I have been looking at. Now I know that I don't look even a fraction like these celebrities, but their hair is to die for! Ahhhh--what's a girl to do?!??!

I've loved this hairstyle for years--this is when she was still with Nick!

I don't think I could ever pull this off-but it is fabulous!
Very cute--My style of bangs!Hair that I thought I wanted--until a few days ago!
