I've learned to let go of any entitlement mentality. If other people don't have to struggle with their weight and I do, so what? Other people struggle with other issues that I don't have to. My job calls for handling a lot of food even though I can't eat a lot myself right now. A bank teller has to handle money all day and not keep any even if she's broke.
I also found the inspiration she drew from her Down Syndrome children to be inspiring. Some particularly good posts: Diet Update; More Diet Discussion; and When Your Spouse is Overweight. Some excellent food for thought (hah!) for anyone interested in the subject of weight loss, particularly from a Christian perspective.
