Negitive self-image

I have been fighting a losing battle with negative self-image lately, and yesterday, I think I figured out why. I was working in the health and beauty department, restocking the hair color isle, when it hit me. Every box I put on the shelf had a picture of a beautiful woman, with flawless skin, amazing hair, and all the rest. Each picture was like water torture, eroding my ability to see myself as passable, much less pretty. I have to keep fighting this feeling. Despair is deadly.
