Kick boxing

So, the plan is to go to my first kick-boxing class tonight. Rhiannon told me she'd go with me. I sure hope she doesn't back out. I'm nervous to go...I'm 50+ pounds overweight. I don't want to look like an idiot. Going to this class is very important to me and to the path that I am trying so hard to stay on. Finding the real me...being good to me. I'll post back and we'll see how the class went.
