Everyone fears the end. When everyone is supposed to die. Earthquakes, tsunamis, fires. Panic rises and people go crazy just for survival. They may even push you in the way just so they can survive. No one knows when it is, how it's going to be. It may be painful, losing your family and dying a painful death. Or if can be painless. Either way we all have to die.
But then there are the people believe that there will be a group of survivors who will rise from the rubble or whatever is left; which won't be much. It will be their responsibility to get along with everyone and repopulate; create civilization. Which could be hard depending who you're stuck with.
Surviving doesn't mean you're going to live. After surviving the disasters, you have worse dangers after you and you have to overcome them. Surviving isn't the easiest. People will die trying to survive. It's going to be hard. But you have to learn to live with it. After all, there is a reason you are a survivor.
