Unproductive in Croatia

Tomorrow morning I leave for my class in Dubrovnik, Croatia. I am so excited to finally be the world traveller that I've always wanted to be... but I am unbelievably freaked out about my checked bag! I am so afraid of it getting lost that I'm having problems enjoying the excitement. I should be over the moon and completely care free about a suitcase full of my stuff. I need to just not worry about it. I should just enjoy this and lay the experience wash over me.
I still have packing left, a paper to finish, and a presentation on God knows what American foreign policy to complete all before tomorrow's flight lands in Croatia. Wish be lick lieblings <3
