Are there lightning bugs in Italy?

I am leaving for my month(ish) long stay in Italy in less than a week. Next Saturday to be specific. It will be my first time flying alone and it is a loooong flight across the globe. I will be taking two classes at The Lorenzo De'Medici School in Florence and will stay in an apartment off campus with 5 other girls. There are roughly 100 other American students in my program, and I do not know anyone, and I'm OK with that.
At this point I am beyond excited about everything! But I have so many questions about so many things...Am I going to make friends fast? What if I get lost in the airport? Are my classes going to be ridiculously hard? Will my apartment be air conditioned? Am I going to get lost in the many unfamiliar streets and alleys? What do I do if I get sick? Am I going to be wired on espresso? What clothes am I going to bring? Where will I wash my clothes? What if all my clothes get lost on the flight over? What if I get stuck by someone who doesn't speak English on the plane? Am I going to have time to just explore? Will I meet the Italian man of my dreams? Am I going to be able to figure out the currency? Will it be really really hot? How much time am I going to actually spend studying? Will I gain lots of weight from all the wonderful food? Am I going to lose lots of weight from walking and sweating everywhere? What kinds of people am I going to meet? Will I learn the language and be able to communicate? Will I have enough room in my suitcase to bring new stuff back? What if I get kidnapped by a family of gypsies? What time will I get up in the mornings? How late will I stay up at night? How much will I be completely on my own? Will I acquire the taste of wine?
Is Florence going to be as wonderful as I'm hoping? Am I going to be taken away by the beauty of the country? How will I interact with all these new people from all over the world? Will God teach me things about myself that I never knew? Where will this adventure lead me? Will I have the courage to really do this? What if I want to stay? Are there lightning bugs in Italy?
