This post contains: Self-harm, Suicide.
I have this really depressed friend, whom we'll call Luna for privacy reasons.
She has a lot of "friends" that abuse her every chance they get, and they have done this for so long that she's used to it. She wants them to do this to her, and I've been trying to tell her that they don't like her, they want a reaction, they want her dead, but she just won't listen. She often ignores me or rejects help when I try to offer. Every time one of her real friends triggers her PTSD, she grabs scissors and cuts herself open, disregarding the effect it has on the others, especially me. I care about her more than any other one of her friends, and she's just rejecting help. She calls herself a tool, and will soon commit suicide if this continues.
TL;DR: Luna is depressed, I've tried to help, she rejected, she might commit suicide if I don't help.
I honestly don't know what to do, and it's now affecting me as a person. I really need some advice on how I can help her.
