What memories do you wish you could make dissapear?

I have a couple. One would be the memories I have of all the negative things my dad has said to me. Another would be past relationships. I guess I wish both of those things had never happened, but they wouldn't make me into the person I am today. So I can't say I regret them, but I would say that I wish those memories would dissapear. I guess over time, well, I hope over time they will slowly start to dissolve of how vivid they stick out in my mind. Lots of bad things happen to people, whether they are good or bad. However, we have the freewill to choose to dwell on those things, or move on. I prefer to try to move on. Which, I have been starting to ever since I came to Liberty and God is working with me too on this so we will see where I am in the next couple years! :D
