Overwhelmed!

I am taking Dr. Tunks and Dr. Kinniburgh's online courses along with 2 others this summer. In Dr. Tunk's and Dr. K's courses we have to have "literature chats" or "book clubs". I am completely overwhelmed by this! It is making me so nervous! I realize the time for the chats is coming up fast and I cannot possibly see how it's all going to work out. I've never done anything like this in a course before. It's overwhelming! Especially two different chats! Oh the joy of summer, online courses! We're almost there though!
