I agree with Albert on the vacation, but with your burnout, you need a looonng vacation, like 4-6 Wk's. Double that would be even better, but may be hard to pull off. Then make the decision when you come back.
As as far as getting help; I know a breeder that has high school and college kids that come a few times a week to clean cages and help with feeding for free. In exchange he teaches them and lets them handle the snakes. He gives them killer deals on rats and snakes as well. The kids are always eager to help.
It sounds like you have already made your decision. That is sad, as many people who turn any hobby into a business find out. The fun just slowly melts away.
