Sorry about the stress your biz is making you pass through. But have you ever heard of WORN OUT? I guess you are, really. If you enjoy what you're doing with the attendant frustrations, fine. But if you'd look else where, I'll suggest you make many from this, hire more hands (money in your bank account can't buy you happiness), and diversify into some other less troublesome ventures. Make money from multiple streams and enjoy your life better. Good health to you.
