This is something I can't really relate to, because even thru my fattest times I still have always taken good care of my nails, skin, hair, etc. I dress fashionably, and still clean my house & make sure my car is clean & the oil gets changed, so why shouldn't I do good stuff for my body as well? Why? Because being fat doesn't make me anything. Except, well, fat. And I'm workin' on that!
I guess it comes down to the simplicity of separating the body issues from the self issues. I've often said that my body image and my self image are very different. I respect myself; ****, I LOVE ME!
My body is fat; my self is wonderful. I have a poochy stomach; I have a good heart. I have bat wings (upper arms) and a keen wit. My butt is a bit droopier than it was when I was younger, but I have strong opinions. See what I mean?
For instance, I enjoy certain activities and so forth regardless of my weight. I know many people who wouldn't be caught dead in a bathing suit simply because they're overweight. They worry what other people will say, what others think, being made fun of, etc. I say screw that!!!! - I love the beach & I love to swim so I'm gonna do it whether I'm 192 pounds or 140 pounds. And if somebody wants to make fun of me because I have chub hanging over the side, then bully for them. I don't go anywhere or do anything for their pleasure anyway.
I'm in this life for me!
