I'm sorry you are feeling bad and colleagues are making it less pleasant. In the first scenario, it just sounded like they'd miss you and thought you valuable. That's how I read it. The second scenario sounds like maybe they understand you need some time off or perhaps they just needed to get the ball rolling with training someone else on your duties. That's how I read it and would try to see it but perhaps I'm way off in left field here.

My ex husband is currently trying to make me feel guilty and bad about myself so yes, I do understand how it feels when people do that. I internalize people's judgements of me far too much. Even if every word and determination they make is erroneous, I still find a way to validate their observations of me. I've only recently realized this about myself and I'm fighting hard to stand firm in who i am....not letting other people's ignorant judgements and observations sink in....especially when they hold these views just to ease their conscience over how they've treated me.

Good luck at your new job Blue.
