I'll go first [CW racism]
"Did you know they just passed a law in Afghanistan that women aren't even talk to each other anymore?" - My Zionist cousin at Xmas dinner.
The rest of the family proceeded to spend half an hour ranting about how terrible Arabs are.
..so, how's your holiday been? 
Yeah. Probably. Then she probably would kill herself though.
I'm gonna pursue the dignitas proof to the end of the earth. When she can't provide it, a real intervention can take place. She can go to therapy, and so on.
And if she really is authentically attempting suicide every 4 months - well, I don't know what I'll do.
Not your responsibility. That’s very emotionally abusive and manipulative narcissistic behavior. I hope you get therapy to help you get through this. Her behavior is not acceptable.
I’m a suicidal person (on and off, currently middling nothing active) and I don’t pull this shit on people. No one (other than my abusers as a child) is responsible for my emotions but me. What happened to me as a child fucked me up and those people who abused me and the others who failed me can rot in hell.
All true, but also easier said than done.
Totally understandable!
