You're going to be fine!I finally bit the bullet and joined a professional writer's organization (more for contacts than anything else). My first meeting is tomorrow, and I'm stressed. I'm terribly shy until I get to know people. What if the other kids don't like me, mom? Or worse, what if I don't like them--my face shows EVERYTHING. I'm all verklempt. If you don't see me again, I died of embarrassment/fear/worry.
