I’ve had this trigger since I was in the beginning of middle school. When I was in elementary I was more of a fighter and wasn’t afraid to fight. However in elementary as I grew up and realized I wasn’t a fighter fighting started triggering me. In the beginning of middle school my dad went to prison so I guess that also effected my confidence a bit. I was bullied a lot and afraid to fight. But beyond that fighting gave me a trigger. It would make my heart beat fast and I would just panic. Whenever I fight videos of someone getting beaten up my brain applies stories to the fight stuff like he finally stood up to his bully but ended up losing the fight and getting knocked out. Even if the bad guy gets beaten badly it triggers me though.
