My dad makes fun of my accent and i want to go home?

You do not say how old you are, but I do know that here in the US if you are a minor (under 18), you need the permission of the person who has legal authority over you to get on a plane. I would love to have you come here, I love the scouse accent. I usually can understand it just fine, but now and then, I may need you to translate. Perhaps you could talk to your mam and ask her to help you go to your nana's. I am sorry your father is being such an ******** to you. I hope things get better for you or that your mam will allow you to go to your nana's. Unfortunately, your father is not the best person for that job. You deserve a caring father. His constant berating of you is abuse. You should contact your school's guidance counselor and see if there is not some way you could get help with that through the school. I hope this has helped. Chin up, Dearie... Do take care, luv, and let me know how it turns out for you!
