Demons (including anorexia) generally aren't inborn. They're planted. By bullies.
And after enough years, when you realize you're in for a lifetime of being mocked, ridiculed and ostracized, suicide becomes euthanasia.
I speak of someone who has spent a lifetime being bullied, not only by my peers but also by my family. I was fortunate to have found solace in my animals. Between my adopted furfamily, a good social worker in my 20s who labeled my clinical depression as situational (as opposed to something being inherently wrong with me), and the knowledge that if I killed myself not only would nobody care, my mother would use it as a way to get attention even while secretly being glad (which helped me project the rage outward toward one of the worst of the bullies), I found reasons to carry on.
Understand that even now, at age 58, I am STILL BULLIED BY MY PEERS. Work only ceased to be hell when I ceased to give a flying fuck and told one of my bullies to fuck. off. He complained about me, but since I had already reported the group's combined sexual harassment, he was told to leave me alone and appears to have been reassigned to cleaning the other side of the hospital or some other cleaning duties because he no longer shows up in the lab when I'm there.
In my world, there are 2 kinds of people. There are people who are civil and friendly to me. And there are bullies. There are no friends. Online is the closest I get to people, because you can't hurt my furfamily. And yes, some bullies are so vicious they have targeted my critters to hurt me.
Do not, DO NOT EVER BLAME THE VICTIM. Because I guarantee that the biggest thing "wrong" with her was she was targeted by bullies. Period.
