This involves me, and my friend's who go by their internet names: Cray, Ruby, Halli (I call her Hall), and Color

I check my messages → Cray quit this whole club thing that I made → Think it's no big deal until I see a shit ton of stuff in my inbox → Reads through all of it and sees that THREE of my friends, not one, but THREE started cyber bullying my friend; which is why she quit the club → Cray sends me messages about her dog having ringworm and that they didn't care (quote from Color: ''WHO CARES HER DOGS HAS A RINGWORM HE'LL SURVIVE SHE CUASE ALL THIS TON OF SHIT''). → Ruby, who was cyber bullying her as well was apparently "complaining about something", seeing as I have yet to gather more information on this dilemma. While Hall (while it's mild) threatened her that she will "punch her repeatedly until she realizes that not everyone will like her". And Cray KNOWS that not everyone will like her.
She starts talking about going to bed and never waking up again.
Note: she's EIGHT YEARS OLD. So I understand that this is a lot for her undeveloped state to absorb. I sent her a message of consolation, but I don't know if that's enough. She used to say that the club was like her family... USED TO. What would you do if you're friends were fighting like this?

It's really tiring being the "person who keeps the rage at bay"... or so a bunch of quizzes and friends have told me. I hope they understand, because I'm a freshman starting high school, and a bunch of stuff is already on my mind. I feel like quitting, but at the same time I know I shouldn't or else I wouldn't be helping anyone, and especially myself.

I feel the most logical idea is to ban them for bullying because it shouldn't be tolerated. You have to man up and put your foot down. They're hurting someone feelings why should you care about there's. Removed them from your group thing or suspend them to behave if you got that choice. I feel like most people would want you to do that. Stay in school don't let problems overwhelm you be a true leader at some point because a leader must know how to think straight through complications.

Hei! that´s really serious! Maybe she has depression or family problems.../(·o·)/...
Well, let´s say she is only a introverted person. Has she tried to enter in any similar group?
I understand you, you have to focus in yourself and your own situation. You don´t have time but at he same time you don´t want her to be alone.
Sorry if you think I´m kind of psycotic but... about that club of yours... maybe you should try to have a external regulator. Someone who will determine if that´s bulling or only a way to end boredom... anyway you should remove them as Roxanne (>>2)said.
Sorry, but you´re kind of general about this topic.
I hope my opinión helps you (anyway).

Arigatou minna ^.^ I feel better after reading that. Thanks a lot :3

(yes, I´m the same one as >>3)
I´m glad we were able to help you!
