HELP!!!

I am Mary, mother of two girls name Rose and Jane. They can be trying. I have tried everything on them and that is what this blog is about. I need help on how to make them behave.

Rose (14)

I spank them and ground them, I yell and scream, but to no avail. I have even made them not talk to each other for two days. Nothing works.

Jane (10)

Rose won't pick her things up and Jane is always off in her own world, paying no attention to anyone. They make me so cross. Even in MASS they don't pay attention!!! What should I do? I need help now!
