Bad memories for me more often cause anger in place of the pain. The good memories cause a bit of both. If all is well, I can look back at good memories and smile. However, if all is not well, such as a past lover or family quarrel, the good memories hurt because there is no making of more memories. Those good times of the past were like promises of a brighter, happier future. When they are ripped away, such as the case of a sudden breakup or a death, they are devastating; far more than bad memories. It takes a lot of time and healing before the good memories can go back to being just that. In other words, when the good memories do bring pain, it is much worse than the bad memories.
