If the truth hurts, how does one accept that truth and learn to live with it?

Most of us have heard the old saying, “The truth hurts.” And in some cases, that can be true. I venture to guess that the truth stops hurting when the person who is hurt accepts the truth and moves on. And there’s my question. If the truth, or reality of a situation or circumstance, is real and not going to change, how does one accept it?

Or is it basically like mourning, where everyone processes the loss in a different way and within a different time frame?
