What is the best thing I can do in this situation?
I've noticed that one of my teaching assistants, who has been around for years, has gained a lot of weight (to the point where it looks life threatening - not to be mean, but to be clear - more than I've seen anyone gain over any summer), and he's been in a very bad mood consistently for well over a month which is out of character (apologizing for outbursts), and I noticed that he works long hours all year round with no breaks (maybe he feels like he cannot take a break to take care of himself).
This is terrific person I speak of. I would like to make things better and not worse.
