Nervous for my Baby Shower

LTLD

My husband's mom has organized a baby shower for this weekend at a community hall. There is estimated to be about 40 people there and 20 of them I haven't even met before.

I'm a bit nervous as I don't enjoy large get togethers, but I'm trying to remind myself this is for baby.

Any tips on how I can get through this baby shower? Anyone else have a baby shower when they didn't really want one?
