All my friends are changing schools :(?

Last year (year 8) two of my friends left. One went to Canberra and one went to another school. This year (year 9) one of my friends is leaving for America and one is going to another school. Only like 5 people left my school and four of them are my friends! how unfair is life :( they're like my entire friendship group and theyll be all gone by next year! and by now everyone else has already settled into their own friendship groups and i'm left all by myself! FML this is actually really depressing. I'm not a very sociable person and i'm going to have another depressing 3 years before high school ends. :( and my mum would never let me move schools.
