Hi Katie. The only one I know of is Michelle Dumaresq. She is Canadian and a m2f downhill biker. I know she made the Canadian team. There is a documentary on her http://www.logotv.com/video/100-woman/1585347/playlist.jhtml which is quite moving.
Also a non olympian I know of is Lana Lawless a LPGA professional golfer from british columbia. Both these ladies had to deal with a whirlwind of critism and setbacks but both are amazing atheletes.
Keep up the great work! xxx Jessica
