My fiance's family doesn't even believe that I weight over 300lbs, but I am tall, so my weight doesn't look that high. I think its sweet that they don't think I need it, but they are supportive none the less. They know I am having trouble having a baby, and they want the best for me and my fiance. I was always teased as the "fat one" and always felt out of place next to my skinny best friends. My main reason though, that I make sure to tell everyone is that I am doing it for my health, at 22 I already have high blood pressure that I take meds for, and I just got perscribed metformin for insulin resistance. If I know its an issue now, why wait for later, when it will only get worse!
