Okay, so I owe a HUGE thank you to Heather, my cousin's girlfriend, because now I can actually breathe when I think about packing. She is a travel guide and spends at least half of her year everywhere except home. She not only calmed me down, but gave me specific instructions on how to avoid lugging way too much stuff around Europe. And surprisingly, I can still take a little more than I initially thought and I was not that far off track in what I wanted to bring.
For anyone who is going to travel, make sure you pack two days worth of clothes and extra shoes in that carry on as well as anything of value or that you don't want to replace. A little birdie told me that airlines and international travel don't bode well for many suitcases. I for one don't want to find myself having to worry about a change of clothes while freaking out about how the airline is going to find my luggage.
So, for now, I have calmed down a bit. There is still 10 days before I leave, so I am sure that will change soon. For now, THANKS HEATHER! My back and my bags thank you too!
