<human>: Could you distill the essence of the text into 1-3 sentences?

I have known this friend since year 10 and we were fairly close until after we graduated. We went to separate universities and we just slowly drifted apart.

I mean we still kept in contact but it was more like grabbing lunch once in a blue moon sort of thing.

Well I tranferred to the university that she currently attends just to be closer to home and we reconnected our relationship. We would have lunch together more often ect.

And during this time I noticed that she had fresh cuts down her wrist. And it wasn't just one or two cuts. But all the way down her arm. I was shocked and confused because I thought I had known her to be better than that, but then again I know nearly nothing about her. I didn't know how to approach her so I talked to one of her closer friends, and they told me shes on anti-depressent pills and she has her ups and downs. 

But each time I see her, her cuts gradually build.

I just don't know what to do. Should I confront her? What do i even say. Or let her other friends be there for her? Or even if I confront her would it help?
<bot>: friend is cutting and I don't know if it is my place to confront her about it. And I don't know how.
