This post originally was posted on Tumblr. I post it here as well (without editing anything as a backup)

While not every resource here will contain explicit triggering content, much of the resources in this masterpost mention or deal with generally triggering material. Content warnings for institutionalized ableism, medical abuse, restraint, child abuse, torture, anti-autistic ableism, “quiet hands”, emotional and psychological abuse, manipulation, infantilization, nonconsensual “therapy”, compliance training, and violence against disabled children and adults.

Resources for therapists/professionals:
