Living with chronic pain: a guide to ACT and pain science.
Short, honest articles for people whose pain has outlasted the explanations.
Everything here is written for someone who has had pain for months or years, has probably been told a dozen contradictory things, and wants to understand what is going on and what actually helps. The approach is acceptance and commitment therapy, the same framework Cindra is built on, grounded in current pain science. No miracle cures. Quite a lot of practical hope.
Start with what ACT is if the term is new to you. Start with hurt vs harm if you want the single most useful idea first.
The last section is for a different reader: engineers, clinicians, and researchers building AI companions. It covers how we are trying to make Cindra aligned, compassionate, and safe, with the evidence and the requirements laid out so other teams can reuse them.
