The weight has been lifted

I left my group....
I probably told you about this but after i decided that i hate this girl in my group and i want nothing more to do with her i left the group. No words or anything, i just realised that i need to do whats best for me and this is it. I suddenly feel like this huge weight has been lifted off my shoulders and i must say it is really nice to be able to come home without feeling bad about something in my group or stressing over a fight or you know..anything. Two of the girls came with me and the rest are just like "what the f*ck".
I honestly didn't do this for anything but my own happiness. I still talk to everyone but the one girl and have a good laugh, i just don't sit there anymore. I am happy at school again and i think that is the main thing. Except that all of a sudden that girl i despise is talking through my bf (one of the girls that came with me) and asking her if i will come and sit with the group tomorrow so that everyone can sort this out. Hello? I don't want to sort anything out at all, i just don't want to sit there and talk to you!
Maybe i should be clearer and be all like "Look you don't like me, i don't like you, lets not pretend shall we?" or just go back to talking to her but only like hi's. I just do not want to be associated with her anymore. I like this better and i will not go back there!
On the other hand, i am worried about sister 3 seeing as she is doubting herself and stuff. There is a girl in her year who is seriously popular and sister 3 was all sad and like "Is there something wrong with me or something"
awww. I'm gonna bash this other girl!
I went and saw the Crucible which was amazing and very dark. All about the salem witch trials which was really cool to see.
