This is all about regret, and looking back. How you can look back at something and all you see is your emotions and feelings and you don't see the facts. How you can regret the things you did or the things you didn't do, and how much it hurts.
It talks about how it's so scary to think that these memories might fade away one day. How it's strange that something so important isn't permanent.
And ultimately this song is trying to tell you not to let regret dictate your future, while still holding on to the memories which made you who you are.
