I'm scared, who's not

The count down to go back in Italy is already started. This experience is almost gone, and I cannot belive it, i remember last year in this period, when I was doing the count downt to come here, to experiece my life, the time was going so slow, I was starting to get ready for the Orientation with the organization for three days, meet the other exchange student, share our feelings, and now, now is just going to be over, to be back to my life, everything will be the same of ever, the same school, the same bedroom, the same streets, everything, the only changed will be me. That's scarry, actually I'm more scared to leave Ireland then when I flought from Italy. When I left I had to build up my life from nothing, and now what's going to be when I'll be back, will be everyting like before? Shall I have to start again my life from nothing, far from the people that make me the person that I am now?
