what is internal family systems 

IFS is a transformative, evidence-based psychotherapy that helps people heal by accessing and loving their protective and wounded inner parts. We believe the mind is naturally multiple and that is a good thing. Just like members of a family, inner parts are forced from their valuable states into extreme roles within us. We also all have a core Self.

Self is in everyone. It can’t be damaged. It knows how to heal.

By helping people first access their Self and, from that core, come to understand and heal their parts, IFS creates inner and outer connectedness. (From IFS Institute.com)
