aniexty attacks aren't always hyperventilating and rocking back and forth
Anxiety attacks can take different forms, such as:
•Unpredictable bouts of rage or irritability
•Nit-pickiness (obsessive behavior, which may be a part of OCD), and even a hypersensitivity to disarray, chaos, or any sort of change.
•Fast-talking, stuttering, stumbling over words.
•Not talking at all.
•Sitting rigid, staring into space, almost seeming "zoned out."
Understanding the way our or others anxiety works can help to decrease the stigma and help calm a person faster and get them out of that state. There are just a few, but it gives an idea of the range in which attacks can come.
