Observation week at work, stressful and sad

This week I had to go through the difficult task known as parents observation week at work. During this week the parents of my kids students, which make up 90% of my students, are invited to watch the class and give feedback on it. Its a stressful week, but its a good chance to show the parents not only how the classes are going, but how the students are improving. Unfortunately, this week was not a simple week of me. Instead it was very stressful and in many ways quite depressing. 

The reason for the stress and depression is that it was decided to make this a week to give me feedback, advice, and a complete impression of my teaching abilities and classes by not only the parents, but by my coworkers at work. I started the week with a major meeting where myself and my managers critiqued one of my classes that had been videotaped. While I did receive some positive feedback from my class, I received a lot of suggestions, as well as lots of negative feedback. All of it was done to help me with my teaching of course, but as the week went on, I kept hearing the same words said to me by many coworkers, disappointment. Everyone was disappointed that many of the mistakes I was making at the beginning I was still making now. It was very embarrassing, and as the week went on, it just kept getting worse. 

Today I finished my final day of observations, and as I look at my notes from the five previous days, and think back to the long and difficult discussions I had the last few days, I wonder what I can do to improve. I'm always told its OK to make mistakes, in fact its expected. But I guess I worry about what I can do to improve my abilities, my classes, and to bring myself up to everyones expectations. I want to improve myself and my students, so I will do whatever it takes to do it. Still, tonight I feel quite sad at how things have gone this week. 

Other than that, the week has been just normal. Quiet at home, and lonely. Hopefully next week will be much better, and that I can improve at work.
