<human>: Had a massive argument with my girlfriend on a night out, after I asked her if she was okay... She was horrible to me, broke up with me and now wants to get back together but thats another story. During this argument she told me she had been thinking about killing herself due to her life "being shit, nothing good in my life". This is a big statement to make and makes me think, saying something this bad and reacting to me asking if she was okay, in such a nasty way, does she need help?

I absolutely adore her, but she's blaming me for everything and the way she talks about killing herself is heart breaking to hear... I feel like I would be a bad boyfriend/wouldn't be able to say I cared about her if I just left it... What do I do? I'm young and unexperienced when it comes to relationships and peoples mental health.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girlfriend flips after me being nice and also talks about killing herself, mentally not stable. How do I help her?
