You need to find out why they have truly banded against you by talking to them - individually. If you approach them as a group, they will not be the best of people to talk to. Have you tried finding out why the initial person stopped talking to you? Or, you can always start looking for other friends... When I had a problem like this, I made it my business to talk one on one to all my friends to find out what what happening. I told them I wanted to know if I did something to hurt them or to piss them off because I really didnt know why they were acting the way they were towards me. It worked. These are friends I have now had for over 32 + years!

What these people are doing is out and out bullying. Given you're at school, you should tell a teacher or another adult you can trust. Sometimes it's hard to admit that people are ignoring you, but these people shouldn't be allowed to get away with what they're doing to you (and possibly others). You should tell your mum/dad/whoever you live with, maybe even a sibling you get on with. It's important you have someone to talk to at home, out of school. Make new friends, or even spend time alone, just don't try to make friends with those idiots. If your friends will fall out with you for no apparent reason, or just because another friend has stopped talking to you, they're not your friends, and they'll do it again. I know it's hard, but you have to take a step back and distance yourself from these people. These friends that are following the friend who stopped talking to you are sheep. Don't let yourself be a sheep. Sometimes going and trying to get friends back makes a situation ten times worse. The people who've fallen out with you will think you're desperate, and treat you even worse. I've been through similar things, and at the time I didn't follow my own advice. When I finally 'woke up' and realised what jerks they were life got easier. If you want to talk, you can email me. If there's one thing I hate more than anything in the world, it's bullies.
