Hi hun,
Don't be scared or apprehensive. Your weight is confidential it doesn't get called out, the only thing that gets said is Df has lost xxlb's this week and mrs D has had a slight gain and then they talk about your targets for the next week, if you have struggled with anything if there is anything you found out that could help others in class. Things like that. It is really friendly and a good way to get to know people in a similar situation to yourself. Remember we are all doing slimming world to lose weight.
