Listening & validating that the things she is going through is one thing, expecting you to solve her problems is another. At least you arent taking her problems & trying to work on solutions for her.

It is good to limit the amount of time spent in a friendship like that.

Ugh, I have a friend who used to listen to someone's struggles then she would think on it & put 200% of herself into figuring out a solution. The problem was when the person didn't agree with her solution (or in my case she had no knowledge of my experiences before moving here) she would get angry.....had a lot of work to do with her to teach her that just listening is OK & boundaries (amount of time with the person) is critical & letting it be after being with the person is important too (not holding onto thinking about their problems after visiting with them between visits)

It's difficult when it becomes like their identity & all they seem to focus on. Trying to do distracting things is good while together....distractions is a DBT skill used to get ones mind off one's troubles......it really helps (from personal experience)
