Wow holly! When was the last time you were measured? I know that you shrink as you get older, but boy, you are just a young chick (and I can say that as you are 6 years younger than I, and in chicken years, 6 is an aweful lot ).
Holly -
If it makes you feel any better, my childhood doctor's height thingee was off by almost 2 inches. All my life I thought I was almost 5'11" But at my first visit to the gyno I was 5'9"! I thought it was their problem but no... I'm 5'9"
That is weird! I wonder if you measured somewhere else if it would be the same as your doctor's office. You should try a different place and see.
I'm older than all of you so I know I'm shrinking. I've always been 5'9" (and I'm sticking with that no matter what!), but when I measured at the doctor's office recently, I was 5'8 1/2" . Gotta start drinking milk!
My best friend was about 5"5 in HS, then she grew to about 5'6 and a half, which she just rounded up to 5'7". I am 5'7" & I can see over her head now, on her drivers license she had to put 5'4". Not sure why it happens, but it's not just you.
