Hi, INTP here. So, I have an ISFJ friend who is an absolute gem. She's hard-working, trustworthy, ferociously intelligent, and just brightens the room. But when she's down, I haven't the faintest idea how to be there for her. :( I feel like there's probably something I could say or do that would brighten her back up, but she and I process things so differently that it's really hard for me to guess what it might be.
So, I just wanted to ask: when you're down, what do you most want to hear from a friend? (Or what is the nicest thing they can do for you?) She's not super-close geographically, so it's easier for me to chat online with her (or maybe buy her something online) than meet up. Anyway, I appreciate any insights you have.
