You gotta think like a business owner / founder. Your product can be open source but how do you want to make money? I doubt that you can get enough donation, at least in a reasonable time, to make a living.

I would reduce working hours, work on your project and figure out how to monetize (e.g. self-hosted vs managed, consulting, ...). What can or cannot work depends a little on the industry you are in and also in what you want.
