Should I ghost?

My family is very distant not even in miles but we only see eachother at funerals...also they are judgemental.

My mom...a complete narcissistic person that has made my life a living hell. As a result I suffer from anxiety, depression and paranoia.

Im a young adult now and ready to live...like really live and be happy. I heard you cant heal where you got sick so im thinking of leaving and never interacting with them again..should I? Or should I leave a facebook up so they get life updates on me( boyfriends, babies, new jobs etc)?
