A family member strangled me as well. It's terrifying, and a way for one person to assert dominance and terrorize another. In fact, a history of strangling is used as by some police departments as a predictor of fatal violence in domestic violence situations. No wonder it still affects us.

I also still see the person who did this to me, for complicated reasons. Cutting family off is hard--there are so many mixed feelings involved. I can't make the feelings go away when I see this person, but I can try to make sure I feel in control as much as possible. So I limit the time I spend, I make sure I am never cornered or alone with him, and I take lots of breaks into the bathroom to do things to stay grounded. I'm sorry you have to deal with it, too. If you're ready, talking about it might be the right thing for you now, at least with your dad.
