How do I keep writing when it doesn't pay the bills?

The work you were called to and the work that pays are not always the same, and right now they are pulling in opposite directions. That gap is real. Feeling worn down by it does not mean you chose wrong. It means you are carrying two loads at once. Try to separate the calling from the paycheck in your own mind. Your writing has worth whether or not the market pays for it yet. The paycheck is a practical problem to solve, not a verdict on your gift. Many good writers have kept a steady job with one hand and their real work with the other. That is not failure. It is how the work survives. Pick one thing this week that eases the money pressure, even a small one, so the writing does not have to carry a weight it was never meant to carry. Protect the work by protecting yourself. The words will still be there when the fear of the bills quiets down.
