Don't ya just love proving them all wrong? My mother was told I wouldn't live to see five (I was two at the time as well, strangely enough) when they diagnosed me with diabetes. Then when I was fifteen they told me I'd probably never have children. And tada! I'm here (at a healthy 25 and no diabetic complications *touch wood*) and I'm pregnant!
My point being, you rock girl! Whatever they throw at you, throw it back twice as hard!
