Well, think it over another time. I have no idea the circumstances that caused you to cut your family off so it depends. What would it take for you to see eye-to-eye with any particular family member once more? What would have to change from the other annoying members of your family before you even hear anything from them?

If you are willing, first see your father one-on-one, set your boundaries clearly and think about them beforehand, what you would be willing to be guilt-tripped into and what you are not, what behaviour is acceptable and what is not. You can keep it just to yourself and your father, and if any others come uninvited or crossed you again in ways you have directly clearly communicated you don't appreciate, then you can block them.
