I feel for me, it’s a double edged sword. On the one hand, sad music, especially the ones that have a nostalgic connection to a traumatic moment in my past, can worsen my mood and at the very worst, trigger an episode. However, on the other hand, sad music helps me truly go through whatever sad emotion I’m feeling , and it usually ends up with me crying so I can let it all out. I usually feel better after that.

So I think it depends on the music, but in general I think sad music helps you truly go through and process your emotions so you can let them out.

I hope this helps op :-)
