Heart pounding, like a drum beating heavily inside. Head spinning, like looking over a mountain edge. Stomach turning, like you've just eaten bad fish. Panting, like you've just ran to the edge of the earth and back. Tiredness, like you've been awake for days. Nightmares, flooding your dreams like watching memories on video. Weakness, like you've fallen from the sky onto your knees. Dizziness, like you're walking through the Sahara Desert. Boiling temperature, like you're laying under the Death Valley sun. Anxiety, like you've gone crazy and can't escape a tiny, tiny cell.
