If you haven't yet, go check out Rampaige's Busty Girl Comics right now! Some amazing body image and self-acceptance comics about women's shapes, and the problems (and perks) they create for the person in that body.
The most recent one, especially, is absolutely fabulous. Look at her belly! Look at her belly! :D Even stretch marks are a part of us, once they're there, and remind us of how strong our bodies are. Love your body, because you only have one. I know it's hard to do sometimes, but it's when you're down that you need the most love, right?
