give the author advice

hi

hello,
So i'll get to the point. I have a suicidal friend that i have knows for a year and this is my last year in middle school. At the beginning we were like friends but then later on she's been getting too clingy, dramatic, annoying, barks for no reason like a crazy person, she's satanic, no one in school likes her because she's so weird and i agree and im sure you would too. So yesterday i tried ignoring her and at the end of the school i went home and she texted me,'why are you ignoring me?' And so on so on until she said,"if you keep ignoring me i'll tell the school counselor and make your life just as bad as mine" and then she sent this text that made me think she was going to kill herself but then i forgave her and she's okay now but i just want to end it. Please tell me what to do.
