School started

I started school this week, one face-to-face class and two online classes. I admit, I've had several panic attacks this week, with the thought of "what have I gotten myself into". I was telling this to my hubby, and he couldn't quite grasp why I was panicking. I believe it is my fear of the unknown, as I have not had experience with online classes, and the need to set my own deadlines is throwing me off. I'm afraid I'll forget a date when something is due, or that there will just be too much work for me to do and I'll fall behind. Luckily, I've been somewhat consoled, as a friend of mine happens to be in my face-to-face class and she too admits to the stomach-clenching knots. I know I have the knowledge to complete the classes, but emotionally I'm still not sure.
