What is it like to break up with your family?

I'm personally contemplating breaking up with my family right now because I realised that all they've ever done is mold me into the person they want me to be and as soon as I'm slightly different than what they'd like, they manipulate me until I go back to my old ways.
That's not healthy.

Have any of you broken up with your family and know what some important steps are?
