(((thunderbear))) - wow you have a lot to worry about and you're justified with feeling overwhelmed. So sorry to hear about your husbands on going medical problems with Crohns and he's lucky to have you and so is your sister. Have you tried simple meditation or breathing exercises? Can you take an afternoon off? Not to sleep and feel sad but to clear your mind. Key thing is to, take things one step at a time. Delegate duties to your sister and husband - explain you need help because you're feeling overwhelmed. In order to care for others, you also have to care for you. Eat well and go for a walk....can you do that?
