I'm just not sure about this ~ it could go either way.
She might feel happier that people care; or she might be feeling depressed and not in the mood for partying ~ and even a bit upset that you have been talking about her, and her problems, to other people.
I just don't know how it will go ~ I hope, though, that it will be successful.
How to prove that you care?
Just by being there for her, no matter what, and by having no expectations and making no demands.
Good luck.
