I too am so very sorry you are going through all this.
What is important is that YOU know in your heart, the truth. No matter what anyone thinks, or says or the gossip that may transpire...your heart knows the truth and you can stand proudly with your head up knowing you did nothing wrong. When we can stand in our own truth, even when we stand alone, we will find the courage to face whatever life hands us.
My prayers go out that those who will decide your fate will be fair and kind and do the right thing and let you continue teaching.
Hugs
