It isn't helpful to engage in one-upmanship when it comes to people's individual trauma. It's alright for people to share their suffering and receive compassion without having experienced the absolute worst possible torture.
"People often tried to kill me." vs. "I worked at a job that paid a wage of 98% above the global mean but had a lot of stress." There's a difference I think, and if it's a matter of one-upsmanship, then we all have PTSD (btw, I don't).
Also he edited his post later so I'm guessing you didn't see the original context.
I'm guessing the GP meant something closer to burnout and was being a little hyperbolic.
Although I think there's something to be said for very long term (years to decades) of high stress possibly qualifying for something similar to PTSD, but of course I'm not an expert on this.
I was not literally diagnosed with PTSD and I apologize. It is not my intention to belittle actual PTSD like you have experienced. A better description is probably "burned out" and I'll change it now.
