I know you have a little life in you yet. I know you have a lot of strength left.

This is about pushing forward, through the hard times, through the months of struggling against the tide. Things will never be perfect, you will always need to fight, to prove that you can change things, that you are better than you were. Pushing through the crap that we have to go through is what makes us stronger, more resilient and adaptable. It's hard to move on, to accept that things happen and you can't change them, remember the past, but learn from it, protect yourself, but not everyone is going to hurt you.
Remembering the past has it's place but you can't spend forever loving a ghost.
