Almost departure time!

So, ready for departure.less than 48 hours. Ticket is printed, money is here, backpack is packed,pick up in Tehran is set, drop off in Barcelona is set. Pick up in Barcelona is set....everything is set. And now is when the nerves start to kick in...will it be safe? Will I get lonely, will I meet people, will it be intresting? This month will be the anniversary of last years elections, what will happend? Im getting a bit worried. I dont know why, all of this kicked in just now, tonight. Im pretty sure the trip will be amazing, but suddenly I have had my thoughts on the trip. How will I feel when being watched my men, by being the foreinger walking around, by taking pictures around.How will it be????? Ill let u know this in the coming up weeks!! Despite all these questions, Im happy and excited. Its holiday time and the moment to go see something new, really really new!!!!!
