In reply to anon (who asked about how to tell the difference between good and abusive OCD therapy): I have OCD & other mental illnesses & have been treated w CBT. Wrt triggering on purpose, nonabusive ERP requires freely given consent to exposure to a trigger & the choice of whether or not to respond to the trigger. Good therapists respect nonconsent, don’t prevent you from or punish you for compulsions, & don’t demand explanations. The irrationality thing is hard. I would try to remember that you have the right to have boundaries even if they’re influenced by mental illness.
