You are very brave and did the right thing by writing us here. I am so sorry you have to deal with your father’s abuse. You do not have to put up with this. You list your age as 14 and your father should not be beating you and saying these things to you. I believe you that these things are happening and you should know that you are protected by laws in your state if you are being abused and you can contact child protective services directly for help. If you need assistance in doing this you can ask a guidance counselor at your school or a trusted teacher to help you make the call. They are obligated to follow up on helping you when there are clear signs of abuse. Show them the pictures.
Here is the hotline number for your state 800-342-3720 and the link to their website. Know that you do not have to put up with your father’s violence. Talk to someone at your school today.
