Calling all ladies who wear heels!!!!

So I LOVE shoes, especially heels. I have a bunch of pairs, but my problem is: 1) I can't walk in them AT ALL. I look stupid walking in heels. 2) They hurt SO bad after like 10 minutes. I even have little 2-3 inch booties and those hurt to. Is it because I'm a little bit thicker? I'm 5'7 and like 190. Is it because I'm heavy? Or my feet? Because I desperately want to wear my cute heels but they just hurt too bad! Any explanations or advice?
