A new emotional symptom after an illness, head injury, surgery or new medicine (crying you can't stop, sudden anger, a flat mood) goes to the doctor first. Some of it is the brain or body itself, and it can be treated. Story and childhood work can come after that check, not instead of it.
P Evidence: promising. Good studies, but small or few. Use it and keep checking.
C Evidence: contested. The research disagrees. Named, so you can stop worrying about it.
