It's kind of a long question. I hope you don't mind.

I have a friend -- at home -- who's good and kind and cheerful. And then . . . I haven't said much about my life, but a lot of things started to go wrong, so from then . . . every time I saw him -- or her -- this person became . . . more and more sad. More and more angry. Less hopeful . . . less happy. And I try to be as cheerful as I can around her, but I don't think that helps at all. And then once, I said that I wasn't very hopeful anymore, either, and now I feel like that was a stupid thing to say, because . . . nothing good comes out of saying that kind of thing. The more I see her, the more afraid I am that I won't be able to help her.

It's been a long time, but I still worry about her. Do you think there's anything I can do?
