You're too young to be deciding to change your appearance. I would suggest you learn to love the way you are. There are many more things in life to worry about than looks.

If you have cool undertones it might look alright. If you have warm undertones, just don't. Also, in order to make your hair that light, you have to bleach it around 3 times the least if your hair is brown or black.
If you think your hair can handle it & if you think it's worth it, be my guest.
