What happened to you is not your fault, and I don't think that your T will feel anything but sorrow that you were hurt and angry that your father would do this to you. I work in family violence, and I think that burning someone with a hot curling iron is a very severe thing to do, and because violence often escalates, you are in serious danger and I would encourage you to stay away and consider taking out a court order of protection. You also might find it helpful to contact the closest domestic violence shelter (they should be able to help you with an order, if you are in the US) just to talk about what your options are. They can also take photos for you, whether or not you decide to make any legal moves or not.

I'm just really sorry that this happened to you. You didn't ask to be hurt, even if you chose to go home. It's nobody's fault but his.
