Sorry for the rant but people who overuse terms around trauma genuinely have no concept of the impact it has on people who’ve experienced the real thing.
Something that makes you uncomfortable is not a trigger. Someone disagreeing with you is not gaslighting. A fight is not abuse. Emotional/verbal harm isn’t violence.
I’ve been in therapy for PTSD for over a year and still can’t put names to things my ex did to me. Seeing people throw around these terms for the slightest things only makes it harder. It just minimises my experience and reminds me that no one fucking understands or believes me or takes what happened seriously.
