I have nothing to show for the last five years but graduate school and I can't finish/want to leave this field
The skills acquired as a graduate student are often very employable outside academia. I was doing a PhD in Linguistics with a focus on corpus linguistics. As part of my education, I learned statistics, Python scripting, Mandarin Chinese and technical writing. Those skills ended up getting me a job offer from a major computer software company, which I accepted and left grad school to take.

You probably have more employable skills than you think. Spend some time thinking about what skills you possess and what professions need those skills. a PhD to your name is not the first thing employers look for - they look for whether you have the skills that they need. 

Stop thinking about your degree and start thinking about your skillset.
