Sorry for the crappy title.

Anyways, on to it.
This problem is something I don't really think should be happening at all, especially at the age we are right now. And mind you, all of these people I'm talking about are girls unless I say otherwise so if you don't like bi people or lesbians don't mention how much you hate them and move on.
My friend, S, likes A. And A likes her as well. But E likes A. Apparently A went on and told E that she likes S more than her. Now E is depressed and A is trying to cheer her up. S is 'dating' SA and wants to tell SA that she would like to break up. I'm not sure whether their dating meant anything. S is scared to tell SA about liking A or about breaking up because shes not sure if SA would even reply to a text like that. And I forgot to mention that SA moved t a year prior so S can't confront her directly. Now A is trying to comfort E an S is feeling very guilty about it. I'm the most worried about S because one time when she found out that someone she likes has a girlfriend, she tried to kill herself. Luckily, the guy she liked helped talk her out of it and she is alive now because of that. And now she is wondering what she did wrong or what she did to deserve this. She wants to say sorry to E but is scared to and doesn't know how. My other friend J feels like if she had gotten to one of them sooner, she could've helped. So she is afraid of them blaming her.
This happened on Thursday but S wasn't told about this until a day after, Friday. That morning, E broke down and started crying. I'm nor so sure about that last part though. I do have first period with her but it happened supposedly before that.
What should I do? Is there a way I could help? They might be able to resolve this by Wednesday, the day we get back to school, but I'm still concerned. I just really hope that this doesn't become known to people. A was trying to keep it as a secret, but S decided to tell me an a few other friends. And I feel that if everyone knows what happened, things could only get worse. So, yeah...I could use some advise. I'm not quite familiar with love triangles and drama so in this situation, I have no idea what to do to help.

Well that's sounds more like a love Hexagon...

But I would just stay out of it and only step in if it gets worse, when something similar happened to me that's why I did, you can't change peoples feelings, if S likes A instead of AS then they do, it just means they aren't the best match for each other and could still be friends but maybe are not meant to date
