Red, Using the Dr. note is good idea. All families need the extra income now but at some point you have to realize what you can handle and cannot handle. Is there any way you can make some extra money from home to supplement less hours?
Working too much when you are already stressed is not good. Do what you have to do to be well. Think of creative solutions instead of worrying yourself sick about it. Hope all falls into place for you, have faith.
