((((ww)))) I'm confused (I know, what's new?) she said what had happened scared her. Is she scared about her reaction, or is she scared about what caused the reaction?

When I first began reading, it sounded like a hit on the head... confusion, agitation, stubborness. But perhaps instead it was dissociation? She's obviously been through alot with her friend, and maybe something triggered her into remembering all the fearful stuff... and to cope, she spaced out?
