The hardest thing about gaining weight, especially when it impacts your health and energy, is how much life you miss out on because you feel self conscious, and don't FEEL like doing anything. I live in the country on several acres, so it is hard for me to imagine how I got to August without having a tan, unless I stayed inside the whole summer...which is probably exactly what happened. I remember going out to weed last summer, and actually hyperventilating because it was so hard to be out in the heat, engaged in physical activity. I blamed it on age, and 30 years of smoking (even though I quit two years earlier). I still have a long ways to go, but summer is a lot more fun when you have at least gotten to the point where you are willing to go out in shorts and tank tops.
