Trying to find my way back to a better career at 30. Starting over feelings super overwhelming.

Long story short I went to art school for biomedical illustration. For those that don't know if you've ever seen anatomy textbooks and patient education diagrams explaining surgeries, procedures, lifecyles etc, that's what we do. I graduate back in 2018. I did a few freelance jobs in the field after college but never found anything that stuck and unfortunately found myself not thinking I would want to pump out illustrations on a tight deadline every day of the week 5 days a week. It was kind of a devastating realization. My first job offer from a medical illustration studio was $35k which is basically poverty wage over where I live. I've been working at a dealership and making double that since then. I don't want to be in the car industry forever and I'm trying to figure out how I can pivot with my science and art background to something that feels more fulfilling and long term. I've been at the dealership for 8 years and I'm feeling pretty hopeless at the moment. I'm highly considering going back to school.
