My opinion/advise is tough it out. Its much harder to go back to school. I quit college after going full time for 3 years at age 22. I didn't finish my degree until age 33.
I could probably be in a way better position if I had that degree 10 years ago. I'm glad I have it now and it's not hanging over my head anymore... but do whatever you have to to finish your schooling, in the end it will be for the best. Can you get student loans? Financial aid? You don't need much to get financial aid, most school just give it to people who want to go to college. Don't worry about your $6k in debt right now... once you are done schooling and get a good job, you will pay that off no problem!
Focus on your BIG issues before tackling little ones... if you try to take on allllll your concerns at once, it will feel stressful and overwhelming for sure.
