Thank you so much for your kind words Lea. You are so right.
I am adding some parts of the Detachment thread that I can adapt to my problem.
The first step to detachment is to "shrink" the unhealthy person. Make the person a smaller part of your life by making other parts of your life bigger.
Adding things to your life automatically reduces the space taken up by unhealthy people and relationships. Expand your horizons. Occupy your mind with new ideas. The unhealthy person will occupy a smaller portion of your mind, and therefore your life.
I will make many activities one after the other so they do not have time to think about bothering me. This will be very time consuming and energy consuming but it is only eight more weeks.
They want to maintain the status quo.
Accept that these unhealthy people (students with narcissistic traits, backed up by their parents at all costs, and teachers encouraging them to be mean to me) will never grant their approval. (No, they will never grant their aproval, no mater what I do, if I do work seets, they complain, If I do transparencies on the over head they complain if I talk they complain if I do not talk they complain) This is a vital part of letting go. In fact, withholding approval is a most effective weapon to keep you enslaved. When you let go, and honestly don't care if they approve of you, they will have a hard time hiding their surprise. Watch as they mentally scramble to think of another tactic to keep you entangled. Realize that the other person's problem (students demanding to spoon fed knowledge with out doing anything on their part) is not yours. One of the hardest lessons to learn is that no matter how hard you try, you can never, ever, ever change how another person acts. The only thing you can change is your reaction to them. You can fight the guilt (and fear to lose your job, and they know they do inspire fear, because they have their parents in the school board) they inspire. You can take care of yourself.
The person you're detaching from can be very abusive. Often, the reward they seek is to see the hurt in your eyes and the feeling of power they receive from being the cause of that hurt.
Recognizing this fact will give you unexpected power. The verbal jab is blunted when you know it's only meant to hurt you. And you can deny them the pleasure they seek. Don't debate the point. They want to keep the topic going because they know it's hurting you. Think of the verbal jab as a spitball thrown at you. If you laugh, or pretend you didn't hear it, or do anything else instead of looking hurt, it's the equivalent of ducking and letting the spitball sail by. Shrug off the comment as lightly as possible, and then bring up a topic of your own -- one that you know is distasteful to your tormentor. Doing this will deny them their reward, and give negative reinforcement. Eventually, they will stop attacking you. Bullies like an easy target.
That is why they asked me to go to the ice cream shop. They enjoy rediculing me, because I show them I feel so bad. They enjoy. If I stop feeling bad they will have nothing to enjoy.
