She's seeking a feeling that has to do with her and her depression IMO...she projects it on to you but she is missing her self-love, her zest for life, her feeling of being inspired. It is her foundation that is off.
Stop beating a dead horse, she is just engraving this story and you should have none of it, IMO. Words will never convince her, experiences might.
What is she passionate about? What inspires her? What turns her on? Until she feels whole, you are just part of her unsatisfying reality...
