A lot of people are sympathetic to the concept of PTSD but not the reality of it.

They expect you to stare off into space or be sad, and they aren’t sympathetic to the angry moments, to strong reactions to triggers, to the paranoia and fear of abandonment, they aren’t sympathetic to the disorders that are often co-morbid like personality disorders, dissociative disorders, or psychotic disorder. There’s more to PTSD than just “being shy” or scared.
