I should start looking for a new job

It's gotten to the point where I googled about depression symptoms this morning.

I've been thinking when was the last time I didn't work on a weekend, that's probably.. the election weekend. And I cannot even remember when was the last time I didn't work on a weeknight. 

It really doesn't help that said equal (or more than that) is actually leaving in a week's time. I have to take over all the work in the meantime, I lose an extra pair of eyes to look at my issues, and I basically lose a work friend. 

To top it off, there are so many issues that I have to follow up with on team management. I may have neglected my leadership duties for the past few months but that's because of the work damnit. Find someone to take over the work and let me concentrate on leading if that's the case. But no, we are always the ones who don't seem to be overworked so just 1 AD and 2 managers are perfectly fine (and now down to 1). 

I haven't really smiled this week, and have had random bouts of mini-tearing. I really don't know how long more I can last like that. Poor husband's been trying to perk me up :(

I cannot see any end to this.
