I hate school so much...i dont have any proper friends and it makes me really sad?

Just to make you feel better.... when you are in a group of friends with 3 or more people many problems rise. It sounds to me that these girls aren't being fair or kind to you. Personally I wouldn't want to hang out with people like that. I can understand that you are shy so making new friends is very difficult. But I think in the next couple of weeks you should try inviting over some of your acquaintances. For now I don't think you should end the friendship that you have with your other friends but I think you should try to become closer with some other people. This will help to make you feel that you aren't alone when school begins. If the problem can be resolved then that is great but if it doesn't then it is time to move on! It may be hard but you don't want to stay friends with people who don't like you! Good luck! I hope I helped!
