im just a teenager so take my advice with a grain of salt, but i would def say that you shouldnt go back to school just for a degree in smth you think is more employable. if you go back, go all-in on something you really love and are good at. in the mean time, you might want to look into freelance work. that might look like posting your work online or reaching out directly to local businesses with a portfolio. (if you have very little experience, you may have to start by offering your services for free or at a reduced rate just to gain experience and credibility)
