What do I do? Friend help, desparate?

First i wanted to say im so sorry about what happened! And that you should maybe call Diana and explain this to her again instead of texting. And whatever you do don't go back to Shannon and Charlie. But, i don't want to sound like a horrible person, but find something out about Shannon and Charlie. Something not very good. And threaten to tell everyone if they don't stop. then make sure u have enough friends around u that you can trust so this won't happen again. I mean this is a difficult situation, talk to your mom, and maybe someone who is a year ahead of you. having someone that's 'powerful' and older as friend might help because Shannon seems to be the type that would want to be friends with older people. if you have someone to quote on quote, lack of a better word protect you, it might help. try everything ;possible to get Diana back. Maybe you have something of hers and need to give it back. its an excuse to go to her house and talk about it. and again, im so so sorry. Plus, this is bullying. Its now illegal. If it gets bad enough, you could do something about it. i know you dont want to tell on them, but if it get bad enough, you might have to. Im so sorry, hope this helped!
