A short while ago I happened to hear a song that immediately made me think of someone that I would now prefer not to be reminded of, as it causes me to feel a whole host of unwanted negative emotions. It wasn't so much the song itself, but the group singing it.
I know it's a long shot, but would anyone happen to know if there is a realistic way to stop the association? Whilst attempting to inflict a brain injury on myself that results in selective amnesia is an option, it is one that I would personally prefer not to try.
