I dont want to be a loner.....?

our registration leader at school left so our registration group got split up and placed in other groups,which have about 30 students in,anyways i only have one friend in my new group and shes being a ***** latley,i know we only stay in them for 20 minutes a day but it sucks,so my friend is going to barcelona for a week next week and i dont want to be a loner on my own,most of them are boys and there are about 5 other more girls but 2 are backstabbing tarts that think im weird and the other two are retards who whisper about everything,should i just bunk off in the toilets?
