Who am I : Quiz Drop for [ June 13th]

The myth goes like this..

I was pure white a long time ago. One day a leapord attacked me and i thought i was going to be killed, but just then a shepherdess jumped in and fought with the tiger and saved me. But Alas, she paid the ultimate sacrifice saving me. In her funeral I wore a black arm band to pay my respect. I was so grief stricken and sad that tears began streaming down my eyes and when I rubbed my eyes the black dye in the arm band mixed with my tears and formed black spots all around my eyes.

I vowed that day never to rub those spots and I have it right till this day! Do u know who am i?
