<human>: First, let me say that our relationship has been long distance for the last 6 months. I'm a freshman in a college states away and she's a senior in high school. We both received full-rides to the same university, so she'll fortunately be joining me next year.

Anyway, she's been depressed for close to a month now. She comes home and sleeps all day, and she doesn't hang out with her friends anymore. Whenever I talk to her on the phone she's extremely unenthusiastic. She's also been complaining and making excuses for herself nonstop. Usually I would say something, but given the current situation I keep my mouth shut.

She assures me that all of this is because she's lonely and hates school. I've been more than understanding and have tried to cheer her up, but nothing is working. Although, she does let me know that she greatly appreciates my positive attitude.

She has somehow lost all of her confidence as well. She claims she's fat, isn't smart, etc, etc. Both claims are utterly ridiculous (she's not overweight, top of her class), but she insists on making them anyway.

With this going on for over a month now, it's getting to the point where I'm starting to lose patience. She refuses to do anything to fix the situation, so now when she whines to me I simply don't want to hear it. I've continued to be tolerant because I know she needs me right now, but I don't know how much longer I can do this. She's not even the same person anymore.

Provide a brief overview of the text.
