A lot of the time I want to be left alone- even though sometimes it is not the best idea. The best thing one can do is ask if I would like company and then just hang and maybe watch tv, go for a car ride, watch a movie... or even just ask me what I need versus telling me to do XY or Z, because I will feel better. It seems simplistic to tell me that deep breaths or a hot bath will fix my broken down self. "Go for a walk" when I can barely get out of bed in my pj's... not helpful.

In summation, I guess asking if I want company or if I think maybe X would help are the best things. Sometimes just hanging out. What works for me though, may not work for everyone else.
