change.

We must be willing to let go of the life we have planned, so as to have to life that is waiting for us.
-Joseph Campell

Change.
Sometimes it's a pretty scary word.

But you know what word makes all of the change in the world not scary?
Atonement.
[the reconciliation of man with God though Christ.]

President Boyd K. Packer taught,

“There is no habit, no addiction, no rebellion, no transgression, no apostasy, no crime exempted from the promise of complete forgiveness. That is the promise of the atonement of Christ”

Through our Savior, Jesus Christ, all change is possible.

"The Atonement of Jesus Christ is available to each of us. His Atonement is infinite. It applies to everyone, even you. It can clean, reclaim, and sanctify even you. That is what infinite means—total, complete, all, forever."  -Elder Shane M. Bowen

He has faith in us. He will help us do the things that we think we can't do. He will guide us by the hand if we but follow Him.
He enabled the way for us to change from our "lost and fallen state" [Mosiah 16:4] and it's only though Him and His teachings that we can change and become the person that our loving Heavenly Father wants and needs us to be.
I know that we don't have to go back to who we were or what we did. With the help of our Savior, we can change.
