Winter Blues

I got a pedicure today to cure my Winter Blues. Speaking of winter blues, I just heard the stupidest term: Seasonal Affective Disorder a.k.a. SAD, are they serious?? Why is it today "they" have to come up with these "technical terms" to describe or "diagnose" everything. Now people who are suffering from "Seasonal Affective Disorder" can get a prescription for it so they're not SAD anymore - give me a break.
