"Just breath" Is probably the most annoy and unhelpful when I'm having a panic attack. I know I have to breath, no need to tell me. I hyperventilate really bad to the point of almost passing out and anyone that's around me typically just repeats like crazy "Just breath" "Take a deep breath" "You're going to pass out"

All the frantic talking just makes me ten times more anxious. I prefer if people just leave my service dog and I alone so she can help me and I can focus on calming down.
