I think it's the same one almost everyone has. Fear of death. I don't fear death for myself really. I fear more what will become of my loved ones after I am gone. Which when you think about it, is pretty selfish.
People go on to live their lives.
Grief is a horrible emotion. I don't like the thought of those I love suffering for my sake. I suppose that is where faith comes in, and it is sad to say, but most of us just don't have enough. I'm going to work on that one. Simple things make me happy.
