*So* sorry to hear this ... I know one feels so helpless. Snatching at positive straws, it is wonderful that your husband is being supportive.
Try not to worry about your job. Be as open as you feel comfortable being .. I think and hope you'll find that most people are very understanding about proper priorities in these situations.
Take care of yourself as well as possible.
