[EMERGENCY] HELP ME

I have made a recent friend from a different country and they are contemplating suicide. They have told me about everything that’s wrong with her life, but she’s made it clear that she doesn’t want help. They want to kill themselves in this very moment. How can I help? 

I’m not trying to do big things like change their mind because that could make things worse. I’m trying to keep them in simple conversation, trying to get them to see positive things around them in the moment, just anything to distract them from suicide.

They refuse to call 911. Their parents are neglectful and their friends are assholes. I am the only person they have. Help.
