As somebody who is not a Christian, I have no fear of heaven or hell. However, if you are a Christian, I would just be the best Christian you can be. In theory, God is forgiving. You will make mistakes, and I believe he is supposed to forgive you.
However, I do not know a whole lot. I'm not a Christian, and I've only been to church services for funerals. But in those funerals, they thought of death as a passage. I would not fear death. If you have done what you are supposed to do in life, you have nothing to lose. Just live life to the fullest.
PM me if you need to talk, I'm here.
