I think trying to remain objective with your emotions and your sympathy while maintaining your own sense of self, separate from your husband, may help. It’s his difficulty right now that you sympathize with but you don’t need to shoulder it as though it’s your own. What helps the most is when one person has troubles, the other person remains positive and upbeat. That actually can help your husband. Just my two cents! I mean you can certainly emphasize with his pain but his pain doesn’t need to be yours too.
