FED UP!!

I am so fed up about the excessive amount of gray hair overtaking my beautiful brown hair. I'm 27 and have no family history of early signs of graying. I don't think I'm stressed, I really just don't know what is going on. I'm making an appointment for some highlights, it's all I can think about for fixing the problem. I really hope I can overcome my madness and realize that it is not the end of the world. For now I think I'm entitled for a little bit of panic. Is anyone in the same situation?
