Are you afraid of death and eternity?

I have been recently thinking about how it feels moments before death. Many people say it is like going to sleep. Others say they see a bright light and something that seems like an afterlife. However being a asleep and being dead are totally different. When I see how beautiful and great life is, I am really afraid to die. Just the thought that one day all of this will be over is really getting to me. Eternity is also a scary thought. When we die its either two things. We will be dead forever or live forever. If I had to choose, it would be to live forever in an afterlife. If there is one. Its really hard to enjoy life sometimes knowing in the back of your mind that one day all of this will be gone. I really want to feel that there is more to this life of ours. That we are just not here to live and die and that is it. If there is a God I really wish he would give us a sign that he is there.
