Ok I have been teary eyed and crying all throughout the day today as well as tears at the drop of a hat for no reason at all for the past 2 weeks.. I have NO clue why..

Is there anyone else out there with roller coaster emotions for no reason?? I normally never cry especially like this. I will try and narrow it down a little so to maybe get a better explantion for this.
I'm not pregnant
It's not THAT time of the month
I do not work
I'm really not under any stress
We have a cruise coming up in January that I'm really looking forward to
Hubby and I are not having any problems
I just don't get it....
