I walked briskly into the cafe, a good book in hand, and ordered a double shot of espresso. I took a deep breath, but that heaviness in my lungs persisted. You know the feeling. Its like there's a lead weight on your abdomen, making your breaths shallow and terse. Like when you get mad. Only I wasn't mad. I was frustrated, and afraid. Work had been pretty stressful, to say the least. I had gone in at five fifteen and it was only now seven thirty.
