You are a soul. Your true being cannot be touched. You should have no fears of the post physical life, only of the pain of this one. You may let the agenda of others hurt you mentally and misguide you. They may cause you mental pain. They my distract you from your mission. Remember, you were not placed on earth because of sins. The earth is not a punishment. It is a chance for you to assist God in the care of creation and even in the process of creation.
