<human>: Could you distill the essence of the text into 1-3 sentences?

My girlfriend and I both age 20, have been dating for about 2 and a half years. She had a strict Chinese upbringing, that left her very negative, and sheltered. Her parents are constantly fight which also puts a lot of stress on her. She feels like she is the cause of it. And her parents don't exactly help, they blame their problems on her a lot of the time (Example:"Because your daughter doesn't get good grades, you did a bad job raising her!" yes her parents actually said this.She constantly compares herself to others and always puts herself down. 

In general the slightest thing will set her off, it can range from "that guy over there looks dumb" to "why aren't you like that girl's boyfriend? ". When she gets mad she bottles up, not a word comes out of her. Nothing will be said until she is ready to talk, its nerve racking. Then when she finally does talk, she explodes: crying, yelling the works. This is when I learn most of what she was upset about. Afterward we'll talk, but nothing ever sinks in, problems are never solved, they are forgotten until they are repeated.

The worst part of it all? She thinks this is an okey way to live. Every time we talk about her anger issues, she says that it's not my problem and I don't have a say, this is how she is and that's that. The few times she admitted her anger is too extreme, I suggested professional help, and she started bawling and said that I'm calling her crazy.

Some of you may be asking "Why do you stay with this girl?". The answer to that is because when she finally gets in a good mood, nothing can bring her down, she can do anything and everything. That is the person I wish I could see more often but I don't know how to go about it. Suggestions?
