I know where you're coming from. As a big girl, I was the extrovert, the one with the big heart, the one who always gave of myself, but since losing weight I find myself far more cynical and have put up walls to protect myself as well. I don't think I'm any less of the person I once was, I am just more careful about who I'm like that with. You will change as society changes the way it views you, and you will find a new normal, I'm sure of it.
