My wife and her family eat anything and everything and are skinny as rails. They have no idea what or why I did what I did and I can't really expect them to. In a way, I'm happy they don't understand as I would not wish an obese life on anybody knowing the struggles internal and external I have dealt with my entire life. It has been an independent journey, but now that I have lost so much weight, they are seeing the person I have always wanted to be and they are now understanding. It's one of those things, I think, that they can't see until you are on the other side. But until then, you just need to push through it and know the rewards will be coming.
They have been supportive because they love me, but that doesn't mean they understand, and that is OK.
