<human>: Condense the text into a few key points

Hi,

I'm a 17 years old boy. Everything goes well. I'm finishing high school richt now (exams). And I have a girlfriend for more than two years now. She has a lot of stress because of the exams, i know it is exhausting but the way she is behaving is not normal.

That's also where the problems start. I believe some months ago, my girlfriend started doing behaving very strange. being uninterested and thoughtless are some of the right words to describe it. We've been arguing for a while now. Everyday that has past, is not a day that has past, but is a day we survived.

She says I don't have to criticize everyday, but I don't do that everyday. What I do everyday is worry about her. The problem is that she says it's all my fault, and the stress and her strange behaviour is something that falls from the sky. 

It has come to a point where she's so mad at me, I start thinking everything is my fault. Deep inside I know a relationship like this is just not meant to be. But I love her so much, more than everything. 

I can't stand that she is behaving stupid like this. The only fear in life I have is not dying, but losing her. 

Someone help us.
