Writing a breakup song doesn’t fix the breakup. It just turns the mess into something you can hold.

Making something out of a bad time does not undo it, and expecting that is how people end up disappointed in their own work. What it does is change the shape of the feeling: a shapeless week becomes three verses with edges, which you can look at, put down and come back to. The relief is in the handling rather than the healing.
Write the thing without worrying whether it is good or whether anyone will hear it. Let the draft be too honest, since you can decide later what to share. Then put it away for a week and see how it reads when you are less raw.
Which mess of yours could become something you can hold?
Free, with nothing to buy inside it.
