I feel so bad, is there anything I can even do?

This girl who's in classes with me I don't know her that well but I know a few people who've talked to her and she's in a sad situation. She was abused until she was 17 very badly and is very pretty but afraid to talk to people sometimes and secludes herself. She doesn't have any family from what people have said. Also, I was walking by her dorm room and noticed her coming back with a hospital bracelet on her arm and some medications. She is always very pale and I think she has a serious illness. She doesn't really talk to anyone. Should I try to talk to her? or just do something nice for her?
