the way she moves ( a metaphor for 'seasonal depression)

The lady is beautiful, but a complication

 And I may never solve her unique equation

 Seasonal depression alters perception

Grabs you by the balls and pulls down

 Not enough to really justify medication

But joy leaves town when it comes around

It forces one to be more intentional

To conceive a reality full of optimism

The lady is a dancer with her own rhythm

Who can ever solve her unique equation?
