I am really sorry to hear about the struggles you are facing. I, too, have tossed around the idea of closing my doors because of bad experiences and rude parents, Lord knows I've had my share of those in the past few years. I hired a helper so I could maintain some sanity and I also started taking more vacation time. Relax, vent, go to the spa and just remember why you are doing this and how much it benefits your family.
