Grab a coffee and think outside the box. Consider your impressive experience and see if you could apply it in different ways.
You're a professional musician, which has given you loads of skills:
You could work with a music charity (which I do sometimes). In Bristol, where I live, there are sites dedicated to youth work, and I regularly see opportunities. It's not amazing pay, but it's better than nothing.
You could move out of just bass, and do some tech work. I'm useless, and I did some work with a PA company. Much was lugging stuff and cable running, but my music knowledge helped.
You may not want to go down this route, but I know a successful function band player who became a booker for other bands. He works with venues and arranges for high-quality bands to come in, and he takes a fee.
If you're a good writer, you can apply to some magazines and websites and see if they need expert blogs written. Sounds mad, but this is how I got started (42group.co.uk is what I do now). OK, it was a long time ago, but you never know.
