For some reason she feels the need to hurt other people to get a reaction out of them. And now she's looking back and realising that she couldn't see the hurt she was doing, because the recipient wasn't reacting the way that she intended them to.
So now she's realised that just because the other person isn't reacting doesn't mean that it's not having an effect and she's feeling guilty so instead of talking to the recipient she wrote a song about it. This way she can make money off the recipient's suffering. But that's just business, right? We all have to make a living.
