What is the point?

It seems like everyone and everything is crumbling around me. So many of my friends and people I went to school with have died in the past few years, and the idea of death is really beginning to sink in. I always try to remind myself that I am going to die someday no matter what I do in this life and its very hard to wrap my head around. I sat awake for hours the other night because I couldn't stop thinking about how I am not the only person who thinks, and there have been millions before me and will be millions after me. How am I important at all? What does it matter what I do? I will not go down in any history books, I will not make any huge innovations to change the world. I am just another guy, searching for nothing. I feel incredibly alone and helpless. At the same time, there is some hope. While many people scoff at religion, it at least gives my life some focus. Following God, loving everyone, and living to serve him at least seems like a good use of my time. If I cant do anything useful in my life, the least I can do is love others and help them to do the really important things. When I die, I doubt I will be remembered, I am just another one in millions of millions of people. Even if I am, what good does being remembered do? When the people who remember me die, what happens then? Will I be flying in the clouds with my friends and relatives having a blast when i die? Will everything just go black and then, nothing? The thing that scares me more than death is the idea that nothing happens after death. There needs to be something after. Someplace where I matter.
