sweetie, you have a very, very important role here. you have to be especially careful. what you have here is a love for someone who can consume you in a bad way. i appreciate you trying to help her. that's the right thing to do, but you need to understand that people in your girlfriend's position really have to get some professional help and they have to desire to get themselves out of their problems too.
you cannot pull her out of this. she has to do so herself. do you agree with this statement? do you understand it fully?
here's another concern of mine. what about this girl is so attractive to you? usually, people we're attracted to are people who we picture as having a lot going for them and people who have personal traits we like. maybe we would even want to emulate some of their personal traits!
in your case, you appear to be very special. you love this girl, but you know that what she's doing is extremely destructive. you're right to hate the behaviour and not the person. i still wonder what about this person is so powerful to you? honestly, it kind of concerns me a bit, because i know how consuming depressive people can be and how they can totally pull everyone around them right down with them.
just be very careful to keep your head on straight and to keep your heart at enough of a distance to allow her to fix her own problems. if she realizes she can take you down and if she knows that you care that much about her, her disease will likely try to take you down with her. not to be mean (she'd never do that...right) but just because there are elements of her disease that lend themselves to consuming other ppl.
be very careful sweetie.
