If the past is following you into your future, you need to let it go. No one has ever proven a benefit to me of living in the past, or holding onto past grudges. In the same vein, beating yourself up for something you did in the past is a waste of time. If there is something you did, apologize and let yourself off the hook. If someone did something to hurt you, remember that YOU holding onto the hurt, anger, bitterness is hurting you, not them.

“The past is over. It doesn’t matter who we are, where we came from, what Mommy said, what Daddy did, what mistakes were made, what diseases we have or how depressed we feel. The future can be reprogrammed at this moment.”   Marianne Williamson

I know, sometimes it feels like you’ve forgiven and then BOOM! Something happens that triggers you right back to that same hurt or anger. Realize and accept that this is the onion phenomenon, and you just have another layer to deal with.
