Oh honey, I wish I could help you. You are in a very bad situation. Does your father know about your abuse? Why would he allow your older brother anywhere near you? You need help so you are not alone. Do you have access to anyone you can talk to? Old teacher, clergy, anyone? How old are you? Who homeschools you, your dad?

I am sorry for all the questions but having some additional information may assist in developing some suggestions.

In the meantime, I am thinking about you and praying for you.

ps...please consider changing your user name. It certainly does not describe you.
