It's loosing all control in your body yet being aware of everything that's happening.
You can't hear your own screams but you know they're there.
Heart palpitations.
Your breathing becomes as fast as your heart rate.
You can't see the people staring but you know they're watching.
You don't blame them, you don't know how to stop it either.
Having a gun held to your chest and being told to run.
Being told your free while being locked in a cell block.
Don't panic.
Stay calm.
"Anxiety, is that actually a thing?"
