When you've been feeling kind of bored/depressed/irritated/generally shitty, and you woke up this morning and decided that DAMN IT, I AM GOING TO BE HAPPY TODAY! and you put a bunch of energy into achieving that goal, even going to far as to smile and laugh and be positive at the afternoon meeting with your least favorite coworkers, and then you get back to your office and there's only an hour of the day to go.... and then a mean client calls you and spends 20 minutes detailing all the myriad ways in which you have failed her and made her life awful. And she's being super mean, and loud enough that you have to hold the phone away from your ear, but she's also right because even though you've tried your best to help her, you have neither the funding nor the staff necessary to meet her needs, and there's nothing you can do about it.
I just feel so deflated. :(
