A Rat in a Cage

Last year, I have made a terrible blunder...
I have overcome it for now...
But occasionally...
The fear do come back and haunt me...
I feel anger and regret over my mistakes...
But then...
Despite all my rage, I'm still just a rat in a cage...
Even if I vent out my anger...
There's no changing what has happened...
The only way out is just to get out of the cage...
In other words...
To fix what's broken in first place...
It wouldn't be easy...
But it still has to be done...
Eventually...
:)
