That is like losing a vetebra over that time. Definitely not normal and something you should check with a doctor.
ive noticed the same thing. a year ago i measured at 5'5'' now however i measure at 5'3'' ........... not really sure how im only 21! help!
make sure you didnt wear boots when you were measuring yourself a year ago.
lol.. Well it's not really funny, I'm sorry. :(
But, I used to think I was around 5'3 or 5'4.. I could have sworn it... and just last month I find out, it turns out I'm only 5'1!! And I'm only 16!
