I got stuck in LA for 6 days because stupid hurricane Irene closed JFK and the numbers my airline gave me to call to rebook my flight were never answered by anyone until the end of my second day there, by which next available flight was 6 days after I arrived. The airline paid my accomm and food but not my entertainment. (I was able to extend stay in the USA and the fare changes were covered by my insurance which I was pretty happy about). I did a bunch of stuff there though. Even went to San Diego.
I was all alone and cried a lot because I was kind of scared to be there by myself. I got in contact with about 5 orgers who unfortunately didn't have time to hang out with me or lived too far away. after that I came home and deleted my org account and took some time off Facebook. Then I got over it and kept travelling.

From my grandma's house to my house it once took 40 hours to get home with 4 flights and looooong stopovers.
