Hve you ever had alot of stree because of an upcoming situation that you had no control over?

All the time! I am a high school senior who also goes to college so Im very stressed out most of the time. On the first day of orientation I was told about how I would have to teach a college class (this was for an early childhood class). I was so scared because Im very shy. Everyday my head was in the clouds, I was so emotionally unstable just thinking about how I would mess up. When the day finally came I did fine, it was a big sigh of relief.
