I still don't understand why creating rumours about your character would be triggering for anyone.

How would a made up stories like "Borun caught a cheater at dice and string him up upside down hanging from the flag pole" or "Borun's horse went lame, but instead of putting him down, he paid a farmer to take care of him for life" bring up trauma? Especially since you're writing these yourself...

Or is the existence of rumours triggering somehow? In which case, maybe P&P RPGs aren't an appropriate activity since a lot of adventures rely on piecing together rumours to identify what's really going on.
