Being completely deaf. My hearing in my left ear blew out when I was being born, so I'm practically on the defense every single day to make sure I don't go totally deaf.
Having my life wasted. I have plans laid out, I'll be going back to school when I move, I'll have a lot more social time with friends. But I have set high goals for myself that I do not know if I will reach. I want to reach them, I have a hunger to hit those goals right now. But I'm always afraid I'll never be able to reach them, and if I don't reach those goals then I will feel like I wasted my life.
