How Do You Cope With Triggers When Helping Others Process Their Own Trauma?

Simplistic was used loosely because in my world, its everything but simple. Its as if I need to be re taught things such as, why humans need to interact, what is a friend and how do we have them without ruining it, and basically way back when clearly I was in survival mode therefore wasn t present in school. I cringe at the thought of what my IQ would be because I remember little about all subjects. I hope this isn t confusing and someone can relate.
