I had this problem to ( Im 14 year old girl ) I had a group of friends and i just didnt fit in well now im with a new group of friends and i love them start by talking to some new friends on facebook and then ask if you can go with them at school and if they agree go with them and if your other " friends " question you on it just say they invited you and you fit in better there , or just say i got invited and i said id would go with them . Dont let them make you feel uneasy , your going to meet plenty of people in your live and if you let them get you down then you will be sad always , so we dont let that happen your new friends will make you forget about your old friends , its weird at first but it gets better alot better x
