If I let go...who am I?

If I let go of the pain that made me strong,
does that mean I have become weak?

If I let go of the betrayals from the past,
how will I guard myself in the future?

If I let go of the anger I hold inside,
what will fuel the fire within?

If I let go of the wrong done to me,
will I make the same mistakes?

If I let go of the person I have been,
who am I?
