Comparing traumatic events isn't usually helpful. You're not trying to heal what happened. You're trying to heal how you react.

Allergies are basically your body's inappropriate response to a foreign body that looks like a threat but isn't. PTS isn't much different.

People who haven't had PTS tend to do a bunch of really weird gatekeeping around PTS. There's really no bar for what level of traumatic event makes you 'okay to be in the club', and that's not a race you want to win at all.

It's way more important to understand how your brain repairs itself on the other side of a traumatic event and how to encourage that healing, because that's where your work is and that work is very similar across all traumatized people.
