Survived my first corporate re-org

I'm currently in my first "corporate" role ever, although I've been a $avage for about a decade now... Anyway, my company reorg'd this week and I survived and it is full of weird feelings. People who have been there way longer than me were let go and honestly it's a huge loss on historical account knowledge and just overall effect to customer service.

I had a big glass of wine, took a breather, and decided that I'm just going to continue to grind and if someday I'm deemed 'disposable' there is nothing I can do about it so I might as well have fun while I'm out here grinding.

Have you all had "survivors guilt" over this type of thing, or have I just been living under a rock my whole life?
