"I'm fine." Stiles had said in his therapy session with the school councilor. "Yeah, aside from the not sleeping, the jumpiness, the constant, overwhelming, crushing fear that something terrible's about to happen."
All this was the result of Matt using Jackson in his Kanima form to kill people. Matt had almost killed Stiles' father, shot Scott, even though Scott was healing due to his werewolf side. Revealed Scott's secret of being a werewolf to his mom. Matt had made the Kanima used it's vemom to paralyse him, resulting in Stiles crawling his way to his father, just to see Matt hurting him. Stiles' anxiety had been through the roof that night. The nightmares following were continuous and torturous.
"It's called hypervigilance, the persistent feeling of being under threat." The councilor had explained to Stiles. *"Yeah, but it's not just a feeling, though. It's....It's like a panic attack." Stiles had responded quietly. "You know, like I can't even breathe." He murmured. "Like you're drowning?" She asked. "Yeah."
You had been there that night. But, Scott and Stiles being as good as they were had sheltered you a lot from it. Keeping the trauma for you, minimal. Of course you appreciated it, of course you did. But at the same token, you could see how much this was affecting Stiles. Really, really affecting him. You finished up at your locker, grabbing your books for after lunch, and made your way to the cafeteria.
