Should I keep on dating this girl or not (although i dont want to dump her), plz read the details of the ques?

Ok. My girlfriend has started getting very insecure about herself, and wants constant reurances from me. She thinks her life is fu*ked up whenever the slightest of things happen. I don't mind girls that are emotional: I talk to her, I comfort her. But I don't like to do this each and everyday, and that is exactly what is happening. I ask her what's happening with her, and when she tells me about stuff like "no one KNOWS her in college, she's just a nobody here" is what irks me. Why do girls want to be someone? I tell her that I love her, and her friends love her; and that should be enough. But she just doesn't get it, and thinks I have it easy in my life when I don't. We've been going out for a year, and this has been happening for almost 5 months now. I want to be there for her from time to time, but I want her to stand up on her feet too. I don't want her to be totally dependent on me, I want her to be happy with herself.
