Getting "The Fear"

I'm in line at the pharmacy tonight, my sick daughter(six, and almost 40 lbs) in my arms. I've been holding her for a half an hour and my arm is starting to burn. They finally call my name. As I step up to pay, with one hand I get my wallet, and dig out the credit card, still holding my daughter with my other arm. She starts to vomit on my back and shoulders and I proceed with swiping the card, signing in two different places answering questions. Line of people behind me. I start to sweat, I can feel it running down the side of my face. Still being vomited on, I notice that the pharmacist has been talking to me. I can see his lips moving, he's right next to the cashier, three feet from me, but I hear no sound coming out of his mouth. I stretch my neck and kind of bug my eyes out and try to focus on him, girl still choking. All I hear is, blah blitty blah blah, something every eight hours, then nothing again. I feel like I'm burning up, cashier looks at me then takes the stylus out of my hand and clicks the final yes button on the credit card machine. I grab the meds, they say thank you,I say nothing. I walk out screaming at the top of my lungs(in my head). I think I just had my first anxiety attack
