aww hun i know it must be terrifying for u but you will have an amazing time once you are there i have family and friends in Australia and they love it. im also same as u my phobia keeps me locked away with no social life and can be really lonely when you have no one to talk to about it. i think your being really brave just think u only live once and this is a experience that will stay with you forever, go for it and enjoy it!!! oh and dont forget to write on here and tell us how much fun ur having
