I am afraid!

Well, almost every human on this planet is afraid of something or the other. Some are afraid of darkness, some are afraid of heights, some of ghosts, some of their parents, some are afraid of GOD and some are afraid of death. Yeah, I am afraid of death if no one else. I dont know why and how this creeped into my mind.... But once in a while there come a period when I cannot think of anything else. I couldnt bear the thought of loosing everything. The fear of loosing the sense of being is unsettling. I try and I try hard but cannot get my head out of it.
I couldnt sleep, something/someone wakes me up. And being a person with less friends, I dont find anything else to divert my mind on to.
I was very young when I accidentally realized how it would be when you die. It's like you are there and then you loose everything, you cannot see, cannot hear, cannot feel and worst of all you cannot think. How is it? Like when you sleep only that you wont wake up again. Its a scary thought if you think about it now. But at that moment of truth it wont be anything.
I dont want to think about it, but it comes to my mind every now and then. A slight problem in health for instance. And I keep thinking of bad and worse things to happen. It goes away after some days, depends on how easily I get involved in other things. But its never easy.
I dont know if there are others who suffer like me, what do they do about it. But would really like to know, not how they feel but how do they cope with it. I dont want to think about death, because of all I do I can never avoid it forever.
[For instance, while writing this; I kept thinking people who are going to die, generally make statements about death. Which are found after they die. I am crap. Somebody help me please :( ]
