This may sound obvious but it’s worth remembering: People will react to this outbreak with different degrees of concern based on factors like their individual situation (for example, do they have kids or other dependents to worry about; does their work expose them to potentially sick people; were they already dealing with financial stress) and their personal characteristics (for example, do they experience anxiety or depression even under more typical life conditions).

It’s easy to slip into criticizing others across both ends of the reactivity spectrum (i.e., “why are you freaking out?” vs. “why aren’t you freaking out?”). That’s especially problematic if family members, especially partners, have different reaction styles and coping methods, causing friction and limiting their ability to support each other during these trying times. Keep in mind that personal coping styles vary and you can’t change other people, but you can make an effort to tolerate different reactions.
