My ex bsf threatens to khs and blame it on me

Lowk I’m tweakin I need someone to talk to immediately.

Her mother is mentally unstable so I became friends to help her out as she was being bullied in school too but she always created problems in class.I blamed it on her family issues and shit.At summer I was pretty busy and didn’t talk to her for a month.Then she suddenly wrote to me and I apologized for not saying anything but then she told me shit like ‘last week in my dream you apologized to me like this then offed yourself.’ So I was like wdym do you want me to do that?And then she just said idc but if I kms then it’s your fault 

I need some tips asap!??!
