>Basically if you like using a medical term to describe your experience ("I'm being really OCD today") I don't think there's much harm in it and you may find coping mechanisms for people with ODC helpful as a bonus.
I was with you up until this point. My wife has C-PTSD, Bipolar type 2 and ADHD, along with what her psychologist describes as "Social OCD". I can't tell you how many times I've had to explain to other people that her mental illnesses are real and some days she and I just can't hang out because she smelled a smell that gave her flashbacks. Because people have normalized the language, they think "triggered" just means upset. For someone with real PTSD, it doesn't mean upset, it means their mind has come unstuck in time and they don't know who to trust or sometimes even what is real. Sometimes this lasts 5 minutes, sometimes it lasts almost all day. She just loses that time, and all I can do is try to calm her down and try to get her to take medication to re-stabilize her.
My wife has been in therapy with a PhD psychologist for 11 years, and only just this year has gotten to the point where it seems like she could probably hold down a job and keep her trauma compartmentalized like most people do all the time. People normalize the language for these debilitating full-blown disabilities and then don't understand the gravity of the situation when somebody with a legitimate mental illness of that sort of degree comes along.
Co-opting medical language for sub-disorder level dysfunctions is bullshit. And that's fine, when you're just bullshitting with your friends or whatever, but how is someone like my wife supposed to be seen or understood, let alone properly accommodated for when everybody thinks they know what a panic attack is but has never in their adult life been so panicked they became nonverbal?
