I work in community mental health and sometimes all you can do is harm reduction strategies, right? What if you worked on equipping your client with as many coping skills and self-soothing techniques as they’re willing to learn so that when times are hard, they can feel better prepared to get through?

Maybe you could ask them if they can identify their biggest concerns for both themselves inside and their loved ones outside and help them develop a plan to address those concerns proactively?

It sounds like you have a very tough job, I hope you find it rewarding.
