I talked to her again a while ago and she said she got really scared and wouldn't do it again, for real this time. I don't know if I believe it though. I just can't let her alone with other people because they will surely make fun of her and maybe abuse her. I know the kind of people who smoke weed in my town and they're not the best kind of people. As of why this makes me want to harm myself, there are two equally strong reasons; I had been harming myself for two years and am now trying to recover. Seeing self-destructive behavior, in any form, triggers me a lot. Also, I have constant suicidal thoughts that make me able to barely handle anything, so being in a situation like that makes me feel this indescribable feeling of wanting to die, like nothing matters, and you're useless, and there's only pain.
