OMG......What am I doing?

OK, so one of the reasons that we moved to Bastrop was b/c there are so many activities for the kids. They put out a catalog of community activities every spring, summer, & fall. The classes are relatively cheap & range from physical activity, to cooking, to accounting & they are offered to kids & adults depending on the age range of the class. It's pretty cool. Sh will be taking Izzy to the dog obedience classes.
Looking through the catalog I decided that I would sign up for a class. Maybe I would meet some people & make friends here. All of my friends live hours from me & I miss having friends come over & hang out. Any way, I considered Yoga but the class is only offered on Sat. morning & we are usually busy on the weekend. Plus, you aren't really supposed to talk during Yoga so how would I make friends? Then I considered Hip-Hop dance, but it is offered Thurs. during the day when I am sleeping after work. Tai-Chi, maybe, adult basketball league, overlaps N's soccer & Sh's dog training.
There was one class that caught my eye, but could I possibly be that brave? Even though I'm an extreme extrovert, would I really be able to step out of my shell that much? I mean, it is something I've always wanted to do. As a matter of fact I often wonder if it was my true calling & I missed it. I get so jealous when I see other people doing it that I almost cry because I want so badly for that to be me.
For those of you that know me well you have probably already guessed what class I will be taking. Public Performance. From what I understand, based on our talents & the things that we learn in class, the students will be putting on a performance in December. My first class is tonight & I'm freaked. What if I have no talent? The class is for teens & adults. What if I'm the only adult? OMG, what am I doing?
