what happens when death becomes her

have you ever just stopped to think that this is actually real life that you are living and that one day you are doing to die. i think bout it all the time and i have no problem with being dead one day my problem is wondering if there really is an afterlife whether its heaven or hell will my soul really be going somewhere besides being six feet in a whole im just scared that theres no afterlife and i wont be able to look down and watch out for the ones i loved and left being is there rebirth and dieing doesnt bother me its the affects of what happens after that gets to me.
