I don't even know what to say and what to do

One of the best bosses I have ever had in my career resigned today. I have to say it has been a rather tough year at my job and this just was the straw that broke the camel's back. I know it must have been a hard decision to make for him and I am happy that he will get to spend more time with his son and wife and enjoy life. I just am very very sad we are losing him - for most of us he was the reason we stayed and believed in what we were doing. POOF, gone..
I am tired, tired of fighting the inevitable. I give.
