lost18, When I first joined the board I read your entire story and I think you are doing great. You are focusing on a lot of good things, and definitely have identified some 180s (you were negative and then you wrote a list of positives). I've done something similar, where I wanted to walk away from the situation knowing that I did everything I could, and it seems to me that is exactly what you are doing!
