Resources
These books are very good. If you want to understand trauma better and how it works, I think they'll help you order your thinking. Reading doesn't replace therapy, but it helps.
If you don't know where to start, try The Body Keeps the Score, Complex PTSD or Ambiguous Loss, depending on what you're going through.

To understand trauma
The Body Keeps the Score — Bessel van der Kolk
The best known of them all, and deservedly. It explains how a traumatic experience is written into the body and not only into memory, and why understanding what happened isn't enough to stop it hurting. Van der Kolk has researched trauma for decades: the book crosses neuroscience with clinical cases and reads without a specialist background.
Trauma and Recovery — Judith Herman
Published in 1992 and still the reference. Herman was the first to put war trauma and the trauma that happens behind closed doors on the same footing, and to describe recovery as a staged process. It is the most demanding book on this list, and the one that organises the rest.
Complex PTSD: From Surviving to Thriving — Pete Walker
For anyone who never lived through a single event and is still carrying something. Walker works with the trauma that comes from what is sustained — criticism, neglect, pressure that never lets up — and describes the four responses we tend to build to survive it. It's written from the inside: he went through it too.
No soy yo — Anabel González
Written in Spanish, for patients, by a psychiatrist and EMDR trainer. It explains complex trauma, attachment and dissociation with concrete examples and without dumbing the information down. González is one of the reference figures on complex trauma in the Spanish-speaking world.
It Didn't Start With You — Mark Wolynn
On what arrives from earlier generations without having been lived: griefs nobody named, secrets, early deaths. Wolynn suggests tracing those inheritances in the language we use to describe ourselves. More popular than scientific, but it opens questions that come up often in session.
On EMDR, and on the parts of you
Getting Past Your Past — Francine Shapiro
Shapiro developed EMDR in 1987; this is the book she wrote for a general readership. It covers where the psychotherapeutic model came from, what happens in a session, and why the work is done on memories rather than on advice. If you want to know what you're coming to before you come, this is the most direct one.
Introduction to Internal Family Systems — Richard Schwartz
IFS starts from a simple idea: inside there isn't one voice but several, and none of them is the enemy. Schwartz shows how to work with those parts instead of fighting them. It sits well alongside EMDR and the two are often used together.
Burnout and migration
Burnout — Emily and Amelia Nagoski
The Nagoskis separate two things we tend to conflate: the problem stressing you, and the stress still circulating in your body. You can solve the first and be left with the second, which is why a weekend of rest doesn't fix it. Written for women, but the mechanism applies to anyone who has been carrying too much.
El síndrome de Ulises — Joseba Achotegui
Achotegui is a psychiatrist, and he named the picture that appears when migrating becomes chronic, multiple stress: loneliness, fear, the fight to survive, griefs that stack up. It isn't an illness — it's what happens to a healthy person under pressure that doesn't ease. It helps to know that what you're feeling has already been described.
Ambiguous Loss — Pauline Boss
Boss studied the griefs that never close because there was never a clear ending. It serves both the person who left and the person who stayed: someone is present and absent at once, and the grief stays suspended, with no ritual and no social permission to name it. It tends to land hardest with people living far from home.
For colleagues
EMDR Therapy for Depression — Hofmann, Hase and others
Edited by Hofmann, Hase, Luber, Lehnung and Ostacoli. EMDR protocols applied specifically to depression, including the DeprEnd approach. Clinical material, not general readership.
Internal Family Systems Therapy — Schwartz and Sweezy
The model's reference manual: the theory and the work step by step. This is the training text, not an introduction.
