Honestly, it's different for everyone. The first step is to break away if the individual is abusive and you have gotten so you can no longer function around that individual. Then you will need therapy so you can access the damage the relationship caused to you as a person. Your goal is to learn better ways of protecting your boundaries, identifying the ways the other person invaded and disrespected your boundaries and developing new ways of defending your boundaries so this individual no longer has the same kind of power over you. It will take you time to regain your sense of self esteem back as that is what toxic people attack the most which is why it takes time to heal and rebuild "self" again gradually.
