How do you find hope in a time of despair?

Have you ever had a time when it seemed that you had lost everything you'd ever cared about, or were about to? How did you get through?

How do you hold on to hope when you can't find any objective evidence that things could ever get better? Have things ever gotten better when that seemed impossible?

Serious question. I'm asking for your own truth, not for advice. So if, for instance, your answer is "faith in God," please elaborate on what that means to you. I am personally agnostic/atheist, but that is irrelevant to the question.

There are no wrong answers. Everyone has their own truth.
