How/if your characters recover from a situation (or resume normal life after any kind of break) should reveal more about them. It will either confirm their main qualities or show how they've changed for better or worse in the course of your story.
How easy/difficult a character finds recovery should also show a great deal about them (and there should be good reasons in the story as to why the character finds this easy/difficult). All of this will add considerable depth to your characters and it is they who "sell" the story, hopefully making it unforgettable for all the right reasons.
