<human>: Can you provide a brief overview of the text?

Here's the backstory. We started dating about a year ago, everything was smooth sailing for the first 4 to 5 months. Then she started to act differently. One day she got in a fight with her mom, who she still lived with at the time and she ended up in her room cutting herself. The cutting didn't stop for a good 3 months. Nothing I tried helped her. Eventually, the cutting stopped. But then the anorexia began. I continued to try to help her, but again nothing worked. She was eating  a maximum of 200 calories a day. Whenever I asked her why she was doing these things she just told me that I don't understand and that she's just screwed up. I thought she acted this way because of the way her family life was, with her mom and dad constantly fighting and all (which I will get into if asked about). 
Then, on Wednesday night she told me that she had been raped 2 years ago. I was in shock, it honestly felt like it was an out of body experience. She cried into my arms for the next 3 hours.
So, /r/relationships, is there any advice that you can give me to help her through the problems that she is having because of this? I want to apologize in advance for my general scatterbrained thoughts here. Also, I want to apologize for using a throwaway. She is a redditor as well
