You can't change past events. That's beyond us. Things happen for a reason and changing it whether good or bad brings only bad news. Of course forgetting that bad situation might help. Using a telepath to remove those memories or use a forget spell. Either way I can't help you on changing the past!

Almost every day I ponder about what would happen if the ability to time travel came true, and I came to the conclusion that it would screw up time's fabric. It would send things into chaos because one reality would happen at the same time another reality would, but you can't have two realities at once, and create a paradox. And anyways, why get rid of mistakes when they are the way we learn not to do them? Don't dwell on mistakes, cherish them.
