I am sorry for your loss and I can only imagine how you are feeling, but please do not worry, I am sure you will have a great time, I have travelled the world with JY and it's such a safe way to travel, I have been to New York twice with JY and twice on my own there is so much to do and see it's such a fun place, so any questions just ask.
Go with an open mind, put your JY labels on your hand luggage to let people know, and remember it takes two people to have a conversation, we old hands just seem to embrace being a single traveller, but we never forget that it's also scary as well..
HAVE A GREAT TIME!
