Hi TheOriginalMe, I'm so sorry you were treated like that
I'm guessing that maybe it left you feeling frustrated, empty, "lost", pointlessness............alongside the hurt?? But please don't base any of your value, any of the value of the past 10 years on one person's actions.
Please allow yourself to be proud of how you came through the up's and the down's, the hard work you put in, giving it as much as you could, your perseverance, your loyalty, the differences you made, your successes, your achievements, the challenges you overcame...........no-one can take the importance of those things away, no-one can really diminish them because they're real, they're yours to keep. And you know how meaningful all of those things were better than anyone, right??!!
And that was touching that your coworkers were nice to you, acknowledged your situation/your leaving after.........and gave you a gift, right? They wanted you to know that you mattered/you matter so let that count too, hey?? They weren't told by management, no expectations on them.........and genuine heartfelt words and actions, hey? And that can be priceless, that says so much about you.
Now perhaps try to make the most of your time off, you've deserved it!!!
And if you can try to look forward to moving to he new team, they're going to be lucky to have you!!!

Alison
