I would deffinetely close. I know you're probably worried about what the DC families will think but can you honestly say that you can take good care of them while poor you is suffering?
Your job is to provide quality care and the most important thing is to take care of their provider ... um, THAT'S YOU in case you havn't noticed!!
Hope you do ok. If you feel you need to go to the ER then by golly GO TO THE ER!!!
