Scared, about going alone?

its kinda pathetic, but i have no confidence whatsoever, but i usually go to cadets, with my mate, but she's not going tonight, and normally this girl who were mates with goes, she's going tonight but normally me and my mate, get dropped off together, and go in together etc.. but the other girl is normally really late, and there's only one other girl, and she's really quiet, so now im scared because the other girl will be late, and i'll be in there by myself, and im normally early, so i'll be in there with all the staff:| and were new, my group, so we all stand in the corridor, and your supposed to go in to the main room, but what happens if i go into the main room and NO ONE in my group's in there?:( and all the proper cadets and staff are in there?:'(
