I need the manual...

Last night my girl graduated from 8th grade.  Not sure where the years have gone, she was in 5th grade when we moved here.  I was a nervous wreck on the way to the ceremony and I'm not sure why.  Was it because she is growing up so fast?  Was it because she is going to be a freshmen in high school?  Or was it because I feel like I am losing her?  I choose the latter.  She loves to hang out with her friends and have sleepovers, she is so unlike me.  I was too afraid to even sleep at my friend's house that lived right.next.door to me.  What a baby!  I wish there was a manual on how to raise a teenager.  I am not sure how much freedom to give her, I stress about everything.  I really miss having her with us but I guess this is just the beginning.  My biggest fear is that she is trying to grow up too fast and she will miss the fun a teenager should be having.  Good, clean fun, that is.
