I also remember your licensing struggles well, liz, and I'm so glad you kept at it and have that on your side now!
All I can say is that it's this company's loss. Maybe you were not meant to stay there--you know how we often say here at SR that just b/c a situation exists for now doesn't mean it will or SHOULD last forever. Maybe that job existed only to see that you got your licensing, and you are supposed to move on now, exactly as you're doing.
