Agreed, not only is our society unhealthy, but we pathologize things that would have been looked at differently in the past just, all the time.

As someone with diagnosed CPTSD, I look back on history and find various characters that I think today would be labeled as such, but they were either a warrior hero (CuChulainn), or a saint (St. Theresa). Not to get too into it, but CuChulainn had a "battle fury" and was known to take a hit and get up and keep going like it was nothing - that's a pretty good description of a PTSD high when there's danger afoot. It's not that you don't feel that you're hurt, it's just that you don't care; it will knock you on your ass later, when the danger has passed. St. Theresa was obviously traumatized (she threatened to kill herself if her parents forced her to marry rather than enter the convent, as a member of a religion that would have believed she would go to hell for doing that; many women were married off to men they didn't want to marry and they didn't try to suicide; that says to me that something happened that she'd rather die than be touched by a man), and then while a nun she would do corporeal mortifications that would sometimes trigger "consolation from god" that she described as "being pierced with a spear of ecstacy" - she hurt herself, her brain sent danger signals, she got a PTSD high, it sounds like to me.

In either case, the high is so good, they attributed it to a deity (CuChulainn was a demigod), but today we're like "you're broken and your brain is in survival mode."
