My question, fellow depressed people, is this: what would you like a friend to do for you that would help with these symptoms? So far I've been inviting her out for lunches/dinners/drinks - I don't always get a reply but that's the depression, not her - and I sent her a personalised Christmas card with old photos of us and a lengthy quote from Great Expectations, a book that means a lot to us despite neither of us having read it because reasons I won't go into here. I hope she received it but I don't know.
I feel like as a friend I can always do more. I will not give up on trying to be consistent through this depression thing, I just need a bit of help figuring out what I can do for her that would actually be useful and not annoying or misguided or just plain unhelpful. If anyone has any suggestions I would greatly appreciate it if you would share them with me in the comments. Thanks in advance Internet people :)
