If you can go with someone that is a big help. I didn't have that, as girls living close by were officers for the next year, and had to go an hour early. I felt pretty 'strange' sitting by myself, but then some women from our church came and talked to me and that made it better.
I would say to take it slow and just enjoy meeting the girls. It will get better as you go more, and maybe you show something. No doubt you will learn a lot, as everyone is always really helpful to answer new people's questions.
Good luck and enjoy!!
