Tools I draw from: 

Psychotherapy: Psychodynamic & Interpersonal Psychotherapy explores the intra-psyche dynamics and their influence on unconscious processes and patterns that influence relationships in order to make them more conscious giving the individual greater understanding and freedom of choice over their behaviour.

Family Systems Theory: Explores the interactive relational dynamics in
families and groups and how the dynamics influence the individual and
the group, and vice versa, to promote deeper understanding.

Cognitive Behavioural Therapy: Focuses on thought processes and how they influence feelings and effect behaviour and how the interconnections can be adjusted for behavioural change.

Health & Wellness: Understanding Health Psychology and related
disciplines of Health Science and how they interact to promote mental
wealth and well being.
