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

I've been with this girl, let's call her Amanda. We are both struggling with mental illness since the beginning of our relationship. I'm diagnosed with Bipolar Disorder and she with persistent major depression.

Here in the country where we live entering in the college is different from the US.

Universities do an annual test, which the content is basically everything we studied in all our years of school and high school plus more. It's really an unfair and cruel system.

The competition is crazy. Entering Medical School in the public system is almost impossible. My girlfriend is trying med school for FOUR years straight. And the failure is consuming her.

It is affecting every single aspect of her life, even our relationship. We don't see each other very often anymore, because the tests started a month ago. However, the tests are not the problem. 

She's distant, like never before. She's not being nice with me and says I'm not helping her. Even though I'm doing my very best to make her a little less upset.

She said she's tired of our relationship, but she also swears she loves me endlessly, i did break up with her twice even loving her because of her studies, but I'm not sure i believe in her love anymore. This last 6 months we barely did sex, she barely talks about how much she wants me to see her or to do anything else in my company...

I'm completely hopeless. She's unhappy and it feels she's just with me because she's afraid of being alone. I don't know what to do anymore. How can i help her if she prefers to be alone instead of being with me?
<bot>: Girlfriend of 2 years is hopeless about her future and prefers to be alone drowned in her sadness instead of letting me or others taking care of her.
