short girl who can't walk in heels

******Just a quick rant because I have nowhere else to vent*******
So I'm only 5'0 tall & as much as I would love to wear heels so I could be taller, I can't. My ankles are too weak and the ligaments surrounding them aren't supportive enough to keep my feet straight when I walk in heels so whenever I put on a pair, my feet automatically twist inwards and I fall. I just wish there was something that I could do to help me feel taller because I'm 21 but there are 11 year olds who are taller than me and not being able to wear heels to look taller at least really sucks :(
