I am angry about a song playing in my mind.
Why does it upset you so much?
It reminds me of the good times my ex and I had together.
It is fine to feel emotions about a prior song that was important to you. Those feelings should not overwhelm you though, just acknowledge them and move on.
I guess, I don't know. It should be over by now.
I think that it is normal to have those feelings no matter how lomg it has been. I think that those feelings are just a reminder of what you went through, it doesn't mean that is currently how you feel though.
