Well, you don't have to be like your mummy at all. You can be the person that you want to be. You can choose what you like and what you don't like and you can choose the things that you want to do.
You are 9 right? Mummies are really really not supposed to hurt their children whether they are 3 years old, 5 years old, 9 years old and even when they are adults. In fact it is against the law for any parent to hurt their child, especially in the way your mummy did to you. That's right, it was against the law for your mummy to do that to you. That law was made because all the people who make laws for England agreed that Mummies are supposed to love and protect their children always and never ever hurt them in cruel and awful ways.

Because your mummy didn't love and protect you in the ways she should have it is more important than ever that all the ones in there with you all help to take care of you now. Whoever told you you shouldn't hurt your throat was wise. You have been hurt far too many times already. Your throat has been hurt too many times already. Maybe one of the others could help you find other ways to be good and kind to you. Maybe a cool ice block would be nice to eat. What other ways could you be kind to you?
