Hi all. So I have a friend who has been pulling back from the world for a while, and is now feeling with long COVID. For context, she's my best friend's wife - I like her a lot, but we don't have a strong direct friendship. She lives with chronic depression (I do apologize if any of my language is off - please correct me if there are preferred terms). I basically want to reach out and say I'm thinking about her, and wish her well, and that she's cared for even if she's not socialising. 

I'm here to ask for advice about the best way to get that across - I'm conscious that being too direct might feel like more of a burden than a boost. Like, "well shit, now I'm obligated to respond to this gesture when I'm already running with zero bandwidth for social niceties".

Can anyone offer any advice or insight? Many thanks.
