On my end, I've written that my meditation practice has been my "saving grace." Okay, if I am going to be honest... it is stronger than that. It has saved my life. With my daughter, I probably would have lingered in a consistent state of depression. I've had bouts, but with my practice I could always get out of it.
Seasonal affective disorder or SAD, is a type of depression that literally follows a seasonal pattern. It systematically appears and disappears at the same time each year. The people who are affected by SAD experience depression-like symptoms beginning in the fall which may continue for five to seven months until spring returns and the days become longer again.
