This is so true. I can understand from first hand experience how being fat might make it harder to feel good about one's self...but so can being skinny, tall, short, pale, having big boobs, small boobs...and the list goes on.
I rarely am jealous or envious of others, its just not something I get to feeling much at all. But I do feel envious when I meet a woman that is big and like startanew said, just shines. She bring such a presence, that you can really tell her weight doesn't bring her down. I think how fortunate those woman are that for whatever reason, they were never told by peers, parents, society, that they were worthless because they area fat. Or maybe they were told, but for whatever reason, it didn't take hold in their self esteem and haunt them.
