PIO panic attack

Mi

Im not a person that is afraid of needles or anything, but I definitely don't like them. I have been good with the Ovidrel, Gonal, Cetrotide, HCG, and Lupron shots. Now its time for PIO. Why is that needle so freaking long? To make it worse today is my 1st shot and i have to do it alone...IN THE AIRPORT. Im traveling for work and my RE says its has to be around 7:00pm. My flight leaves at 8:00pm so there is no way to get around it. Im scared for the shot and grossed out by the airport bathroom. What am I going to do?!?!?!
