Ms., Lange if you want to salvage your career move on and make a mark of contribution and excellence in your new environment. Sometimes taking a loss is tough but still offers answers to how things went off the track. You had your "day in court" and are unhappy with the outcome. I live near Page school, not that I have any special insight into your career there, but one of your biggest hurdles was there were a great many staff who were not in your corner...not your biggest fans let's say. If you want to be successful and not fail again look into what the inter-personal issues were and learn from those. 
Continuing your "suit" will only find you in a deeper hole....as your case has been already tried. A failure in leadership..use it to do better next time.
