I don't like my friends anymore.?

I have the almost the exact same problem with my friends. My friends have gotten extremely fake this year and all the talk about are themselves. I would keep doing what you are doing. if they ask again tell them you want to get into a good school and that you care about your future. you can also tell them that you are having a great time with the other people because they don't talk about you behind your back. that is what i would do. they are not worth your time and effort if they keep this up. they are not good friends. hope it all works out.
