thanks for the replies...
no thinking this is not a natural thing...i have something called vitiligo, its a skin condition in which you lose the pigment (natural color) in your skin and basically end up with white (as in bleached white) patches on your skin. It can spread throughout your body, changing in shape and size. It's trigger to grow is said to be stress of which it usually causes more. It has no definite cure and greatly increases one's risk of skin cancer.
Many people are so painfully affected by this that they decide to undergo treatments to completely bleach their skin so the color discrepancy doesn't show. One example of this was Michael Jackson. He has vitiligo, which started on his hand (hence him always wearing a glove).
Unfortunately, I have one of the worst cases of this and have white patches all over my skin except for most of my face. This skin condition, which i've had for all 18 years of my life, is the real cause for my insecurities.
Google Vitiligo if your interested, tho there is not much more out there too learn except sob stories.
