friendship help

ihave this friend who is aways say the group loves u why isolate ur self and sit by urself but then she back stabs and i hurts to now the real person i dont noe if i should tell her how i feel or just leave it

well i think you should talk to her and tell her how you feel
if she doesn't change then find some new friends
i know how you feel though-my friend did that so i found new friends and now they are better than she ever could have been
it'll be ok

and more sry......i don't think you should just leave it cus then you'll be sitting by yurself and you'll be miserable
change the problem now or it'll just get worse
i know this from experience!!!
