My life was basically filled with traumatic incidents. Some stand out more than others, some I've blissfully managed to repress or mostly dissociate, some I've worked through (or am in the process of working through). So I would say, 'I have lost count'. I tend to try to move forward however possible. I'm honestly not able to speak in numbers on this.
I'd never judge 'high numbers', because after all with experiences as slavery, war, and the like? It really gets to be a high number. I wouldn't discount that people think of their experiences, and daily realities, as traumatic incidents on their own, when they are that. They're entitled to think of their traumata however they do.
