That explains a lot... For the last week (especially) I've felt irritated, had uncontrollable outburst (so bad that I almost broke up with my 7 yr relationship with my fiance'), crying, mood swings, and a feeling of being constantly tired. I would consider myself to be very sensitive to weather fluctuation due to the fact that I get massive headaches when I go from hot to cold temperatures or vice versa.
This is a very interesting post! Keep up the good work!
