You have nothing to worry about anything out of life.
If you do worry you only have two things to worry about; if you are sick, or not.
If you are not, you have nothing to worry about. If you are, you only have two things to worry about, wether you will get better, or not.
If you get better you have nothing to worry about. If not, you only have two things to worry about, wether if you will live or die.
If you live you have nothing to worry about. If you die, you only have two things to worry about, wether you will go to heaven, or hell.
If you go to heaven you have nothing to worry about. If you go to hell you still have nothing to worry about because you will be too busy meeting all of your old friends.
