Right now it sounds like she's in a MLC. Have you read up on it?
Unfortunately there's nothing you can do to change her path. Start living for yourself. It doesn't have to mean getting a D, but if your life starts turning out well, who knows? You might find someone else, your W might notice you, etc. No one knows.
Just take that step to live for yourself first and go from there.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
