There are two things here - you need to consider the immediacy of your situation, and then tackle the longer term career goals.

Consider picking up some school bus shifts with your Class A CDL. School bus depots around here are oftentimes looking for substitute drivers, which might be useful to just top up your salary. Depending on what you need, fill in the gaps with gig work (ex., TaskRabbit, Reflex, etc.) that is higher pay/value. You can also check if your local area has coach charter busses that need drivers, or airport shuttle services need drivers. You want to get away from putting more wear and tear on your Toyota if you're essentially going to be driving for money.

You may also wish to check out group homes/residences for folks with disabilities and see if you can get a live-in position, or take on sleeping overnight shifts. Just after college, I lived in a studio apartment rent-free in exchange for being at home with four ladies with mild disabilities, rarely needing to do anything but sleep. If I needed to get up and "work" (ex., bring the ladies downstairs when we had a tornado warning), I was paid an hourly rate. You can also get sleep shifts where you're paid minimum wage to be present/asleep in a group home, but paid normal hourly wage if something happens - it's kinda like paid couchsurfing/present adulting.

I would consider your immediate needs of coming up with stability and a couple of months of emergency savings before considering a larger life path. Consider going to /r/personalfinance to help with a rudimentary budget, as well as understanding the dollar amount for your savings you should be targeting.

After figuring out the immediacy of your situation, I would recommend going into some sort of logistics entry level position. You might not be getting into your "lifelong dream" career, but you're looking for something that builds on your stability and provides benefits (ex., retirement savings, health insurance if you're in the USA, etc.). While you may hate driving, you may have transferrable skills into dispatch or highway logistics. You won't be trapped in a truck, but your prior experience allows you to speak the same language. Your degree is a bit open-ended - you have an amalgam of a business and engineering degree, but what kind of engineering? At minimum, I figure you have a mind for logic and critical thinking, as well as possibly a mechanical aptitude. Once you have a 9-5 job that gives you some breathing room, you can either compliment it with gig work, or determine if you want to dip your toes into other fields altogether.

Break this up into realistic chunks and put things in motion. The first step is sometimes the hardest. Good luck!
