Dr. Nicole Lepera

Trained as a clinical psychologist, built a very large following as The Holistic Psychologist, and wrote How to Do the Work around self-healing, inner child work and what she calls trauma bonds.

The book sold enormously. It has also drawn sustained objection from other clinicians, who argue that encouraging people to heal themselves without a therapist is unsafe for the population most likely to buy it, and that several of the concepts are presented with more certainty than the evidence carries.

Useful as a vocabulary for noticing patterns. Not a substitute for treatment, and worth reading with that firmly in mind.
