I too get extremely obsessed about certain songs at times. Ones that touch me deeply emotionally. Last week I drove in circles for over an hour listening to the same song on repeat. I was crying with profound joy and sorrow at the same time. Coincidentally, today I was listening to ‘Grey’. This has been happening for a few weeks and gets intense. I guess I’m saying I understand a bit of what you are experiencing but don’t know what it implies for you. For me it means I am apparently in a episode of some sort and could be getting worse or better.

Don’t make rash assumptions. You may get through this ok. Still, contact your pdoc now if possible. Best to get on top of this ASAP. Take care.
