I believe this song doesn't necessarily need to be only about a broken heart because of love. It can speak to everyone who goes through hardship and struggles. Whether it is a conflict with yourself or with another person, there will always be challenges. We shouldn't back down just because something is hard. Usually, good things are born when we fight through the problems and stand up as champions. So fight the good fight but don't lose sight of the light which waits for you at the end of the tunnel. Trust me.
