Preaching To Myself: You cannot undo your past. You cannot change what hurt you. You can only go on from where you are. No, it's not easy. It's terribly hard, but if you want to be happy, if you want to live a fulfilled and meaningful life, you cannot squat in your past, reliving each hurt and using them as an excuse for never going forward. The world will leave you behind. This life is not a dress rehearsal; there are no do-overs.
Take a deep breath. Take another one. And then take the first step forward. It will be hard, but it will get easier. God will be there right beside you. Sometimes pushing you, sometimes dragging you (as my friend Jolene said), but He will be there.
