It is important to recognize that having a longing for life after death is a good thing. C.S. Lewis once wrote:
…a continual looking forward to the eternal world is not (as some modern people think) a form of escapism or wishful thinking, but one of the things a Christian is meant to do. It does not mean that we are to leave the present world as it is. If you read history you will find that the Christians who did most for the present world were just those who thought most of the next (Mere Christianity, [New York: Macmillan, 1952], p. 118).
