From the article:
Symptoms of PTS Increased anxiety and emotional arousal
- Hypervigilance (on constant “red alert”)
- Feeling jumpy and easily startled

Other common symptoms of post-traumatic stress disorder (PTSD)
- Guilt, shame, or self-blame
- Feeling alienated and alone

Symptoms of PTSD in children and adolescents
- Acting out the trauma through play, stories, or drawings

The "floor games" she plays with the tiles in the school hallway suggest that she might be acting out her past trauma in some way. I haven't completed the path yet, but it's not too uncommon for children with PTSD to do similar things.

The fact that I display literally every one of these symptoms concerns me.
