In my new role I am meant to take over some of a coworker's duties.
They are way behind on these tasks.
I was told to treat them compassionately because they are going through a personal crisis.
But they also seem to be more or less incoherent about work stuff, and also to be sacrificing their own needs e.g. sleep, for work.
How can I best function minimally while also not losing my mind?
I am pretty assertive and confident at work and in general, however with that I often empathize strongly.
