Scared to die, is it normal to feel like this or am I over reacting?

Asked: Scared to die, is it normal to feel like this or am I over reacting?

Several kids that have gone to my school or live in the area or somewhere near my school district have passed. I'm a sophomore in high school and all these losses are changing my perspective on things…especially since everyone keeps bringing them up. (car wreck, suicide, cancer, and shoot out. causes of death in case you were wondering) and I just have this strange feeling that I'm next. I'm a healthy girl, active in sports and not overweight. I have no fatal illnesses and you'd think that's be enough to reassure someone they'll be fine..but I cant shake the feeling. I'm scared to die, not only because what if there's nothing beyond this..the earth, just eternal darkness and the effect it would leave on my loved ones. Also, I keep thinking about things and they happen. For example, I was thinking about table etiquette classes (I know I'm weird) and if they teach not to spill drinks on the table…the next day my cousin spilled her drink on the table. Also, I was talking about Coldplay and later on I was watching Tv and the show I was watching started talking about Coldplay…I know this sounds irrelevant, but things like that keep happening and it's making me even more scared, like maybe God's trying to send me a message or something. I know I sound silly, but I want to know if anyone ever feels like this or understands where I'm coming from? If so please respond and with advice on how to overcome this faze and what you think of my situation. Personal experiences would be GREAT too. PLEASE RESPOND.

Ps. don't scold me for putting this Q/A in singles and dating…more people seem to look through these questions.
