My diet hasn't changed, still eating 90% awesomely, drinking well, nothing crazy.

Life has been a little stressful (I'm branding an entire company before October 1st for the first time, and planning my first big event for January)

But I've been so sweet and happy with my guy some minutes, and totally crappy and depressed most hours, randomly throughout the day.

Period ended two days ago, and I just don't get like this.

What the fudge is going on and how can I fix it
