Who'dve Thunk It?

Ok, I never imagined that I would get so much feed back from my coworkers and staff about leaving my current position. I'm overwhelmed with all the immediate reaction of what???!!! to the next expression of, I'm so happy for you...you deserve it...to their lament of "what will we do without you? " I have spent four really great years working on a floor where I enjoy the people sooooo much that it almost makes me cry to think I'm leaving it. I have an absolutely fantastic and supportive boss now. I look forward to the new challenges and the opportunity to not be so tied to my computer (I'm a database specialist now) but never imagined I would have such mixed emotions about leaving. Who'dve thunk it?
