After reading your post, my first thought is.... whatever you do.. do not go back into the classroom. Children in the classroom deserve to have teacher who WANTS to be there, WANTS to teach and WANTS to help children. You clearly do not want that.
I agree that tutoring is a good avenue for you. However, you are very quick to drum up excuses as to why you could not tutor based on hours ,etc.
My suggestion is to sit down and go over your budget with a fine toothed comb. Figure out what your truly NEED and what you really just WANT.
Does your house NEED to be renovated right now to maintain safety for your family or do you WANT it renovated so it is nicer.
Think about delayed gratification. I feel blessed that I was able to stay home with my daughter. I would have sacrificed a lot in order to have that opportunity to be with her which means income, vacations, extra movies, restaurant dinners, etc. Your children are only small once and then the opportunity is gone.
I am not sure what you want. It sounds like you want to work but hate (or burned out)of your profession and you don't want to be around children in classroom setting.
I hope you are able to sit down, look at your situation and figure out what is best for your family.
Good luck
