You were kind to ask her round! I admire you for doing that so promptly and for obviously having her best interests at heart.
I wasn't clear from what you wrote whether at the end she complained because she didn't get to talk about what was bothering her, or she refused to talk?

My own life experience is that I went through a couple of years where it was very hard for me to take responsibility for my life or my feelings. I wanted other people to make it all better. They tried but they couldn't: some life issues like finance are as painful as banging your head against the wall, there is no answer except perseverance.

Sometimes people lash out at friends who want to help. Personally I wouldn't be able to put up with that. That's not a judgement but my limitation .
