What's your worst fear??

I have a lot of fears too, even though they may not seem like a big deal to soem people, to me they are. My little fears are of needles, and the dentist. My biggest fear is of losing someone close to me. I went through losing all of my grandparents as a kid before the age of 11, and it has since been a big fear of mine. The thought of not having someone around that I'm close to and am used to seeing on a day to day basis scares me beyond belief. I've came close to losing my mother a few times, and it was something that was really hard for me. I couldn't imagine of anyone not having the fear of losing someone close. Unless they don't let themselves get close to anyone.
