You're the only one? Weird, there are a bunch of other souls in this body with me. Usually they let me run things, but every once in a while they take over a tiny bit just for kicks.
The body does not clothe us, we embrace the body. We identify with it. To many it is the only substance of self that can be imagined. There is another sense of self however that transcends space and time. This substance is commuted to us through mind. The continuity of self lies in the community of mind. Not one individual we have ever set sight upon has ever ceased to exist in relation to this substance. The despair of death is an anxiety founded on false assumptions. The pain of parting does not come from physical dissolution, but from the active denial of existence based on the evidence of the body.
This question used to haunt me as well. Literally, I could never enjoy my time...awful thoughts would just hit me. Especially at night. Forever is a long, long time.
I have never been sure about this either. I sometimes thing that perhaps there is a heaven, and it would be nice to know that after this life there will be a perfect, peaceful life. But, then sometimes I think that perhaps there is reincarnation - that would enable us to learn about what and who we are in this life. And then of course I sometimes think that there might not be anything after this life, and that terrifies me. I guess it's something that we won't really know until it happens. But then of course if we are reincarnated or just dead - we will never know :S
