Saying Hi

(Imagine timid hand raised)
Saying 'Hi' for the first time. I've never done anything like this (at least not with an online forum). I'm in my early 30's, a wife of 15 years, mother to three (ages 3-11) and full time RN and Homeschool teacher. Needless to say that diet and exercise are often hard to do right with my schedule.
But I'm motivated. I'm only a little overweight. I'd like to loose between 8-15 pounds. Obesity and the related health issues run deep in my family so I really want to keep myself healthy for as long as possible.
