My friends always put me down, I have had enough but still want to be friends with them...?

If you spend time with these girls outside of school, you probably don't want to let them go because you hate being alone and always need somebody around to ease the lonely feeling. These girls are not real friends and obviously are very immature and insecure. Spend time getting to know the girls you spend your recess with and invite them out as a way to get to know them. Usually people are a lot different to how they behave at school. You don't need people like this in your life because it will only make you feel worse about yourself, just like how these girls want.
