It sounds to me like you were there for your friend. Sometimes a person can be so challenged with things going on in their life that they need to engage in something different that provides them with a break from all the challenge and stress. She came to you crying and then got a chance to experience sitting with a friend and talking about other things which gave her a break from all the things that were challenging her. She may have needed that more than to just sit and talk about all these challenges which is why she got short with you when you tried to get her to sit and talk about the things that she was struggling with. That added to her thinking about not really getting a break and feeling heavy hearted returning to her very challenged life. If she talked about other things then it may have been what she needed to do to get a break so all the challenges don't end up definining all of her.
