I'm sorry that happened... must make day-to-day difficult if you are trying to avoid music that is triggering but always present... I wonder if the music just allows you to feel, and your head jumps to negative emotions? Are you able to express the emotions in other ways?
Music has changed over time for me (and continues to change). If I am down and listen to certain music, it brings me up... but on some occasions, that same music can bring me down hard and fast, and other times it does nothing... Is there a way you can consciously change the thought patterns when listening to the song? Does recognizing the pattern and maybe talking back to it help? Something along the lines of "This is just a song. I don't have to express my feelings in this way..."? I dunno... something to stop the cycle? Does talking to someone about it help? Would writing to someone about it help? I know for myself, it helps to write to my T and tell him my line of thinking... it generally pulls me out of it knowing that someone in real life now knows and will hold me accountable for it.
