A Mood

For the past couple of days I have been in what my mom would call "a mood."  You know what I'm talking about right?  A bit whiny and selfish, only want to do what you want to do, maybe a little lethargic (or hyper depending)?  Yeah I'm in a mood... Maybe a better way to describe it is all I want to do is act like a 2 year old and throw a tantrum for no reason...oh see now you know what I'm talking about. 
It all started Thursday.  I had a doctors appointment and had to leave work early.  No big deal, I have all sorts of sick time and never take off without good cause my boss totally understood!  Then, my co-worker who already was taking Friday off and had already taken 3 days off "to move" wanted to leave early on Thursday too..This just annoyed the hell out of me.  (I really don't know why other than she annoys me because she takes advantage of our bosses generosity so I feel like I work harder/more than she does--which I do but I also make more...)
Then on Friday when it was supposed to be my boss and me all day my boss was sick so it was just me for most of the day.  Usually I love days that are just me in the office, I get so much more done! And Friday was no exception, I got a ton done, but I just felt off all day.  I did not want to be at work I just wanted to go home and curl up in bed and ignore life.  And Friday night that is exactly what I did.
Saturday I woke up still in a mood...so I decided to watch a bit of tv before heading to my coworker and best friends apartment to help them move.  I went and helped them for about 4-5 hours and shocker my coworker annoyed me again, this time because while everyone else was carrying her shit up and down 3 flights of stairs to get her moved she was inside in the a/c "cleaning." But it totally wasn't worth the fight so I just kept counting the calories telling myself it was better for my health anyway...Then I escaped to go watch Harry Potter, surely to goodness Harry Potter would put me in a good mood!  Nope--Because I was so sweaty from all of the trips up and down the stairs I got cold in the theater and couldn't shake the chill once I got home.  Don't get me wrong, the movie itself was great and it was wonderful just to escape and eat popcorn, but I was still in a mood.  So I went home, watched tv, realized I wasn't going to shake the chill, took a LONG HOT bath and went to bed thinking I would feel better in the morning.
Sunday I woke up THINKING I had beaten the mood--yet somehow all I accomplished all day was eating a ton of food both healthy and junky and making myself sick to my stomach...I made ravioli from scratch which was amazing, and really the highlight of my day, but still at bedtime I was in a mood.
Today I woke up sick to my stomach (self inflicted due to all of the food yesterday I'm sure) and ended up taking an hour of sick time to let the pepto kick in.  But I am still in a mood.  (and for the record my co-worker is actually working today and hasn't done anything to annoy me so it's not her this time!)

Have you ever just been in a mood and not really known why or how to get out of it?  How do you beat the funk?  Any comments/suggestions are very much appreciated!
