Sometimes a therapist is needed to gain this kind of insight. Often we grow up disliking several of the roles we adopted in our family. These roles may even continue whenever we return home years later. You may be uncomfortable with the role the family continually assigns to you. It may take considerable awareness of what's happening and effort to interact differently in order to break out of your assigned family role.
Life is bigger than just one role or one relationship with one parent.
Breaking away from parents means being free to grow and develop new roles and relationships, as well as establishing good, new, and different relationships with both parents.
