Depression is a serious illness. While SI is sometimes learned, depression isn't something that you just pick up from someone else. My guess is that it would have probably happened to her anyway, but since she has you as a friend you two can support each other. You really can't take the blame for her problems - there are too many factors to blame anyone, including chemical and genetic factors.

The best way to influence your friend to get better, though, would be to work on getting better yourself and see if you can bring her up with you. It's scary to ask for help and see someone about mental health problems, but that really is what you need to do. It's really not that bad.
