I'm 4'10 1/2 (yes the 1/2 counts), and I've come to terms with being short. I have NOT, however, come to terms with having gymnast style features (read HUGE thighs and no boobs) when I'd love to have the legs that look good in "skinny jeans". Oh well. At least once I get fit, I'll look ripped as well.
If you can spend years beating yourself up mentally and remain standing, you can HANDLE a few muscle cramps and cravings. A little pain has NOTHING on feeling insecure. Remember that next time you wanna quit. You can do this!
