Is it the winter blues, is it stress or is it clinical depression? One in four patients has the “wrong” condition after seeing a professional, according to a study. Symptoms are feelings people experience every day – sadness, unease, worry, and bad temper. Many patients feel tired all the time (how many times have you said that about yourself this week alone?), can’t fall asleep or sleep all the time. And if the multiple symptoms are not enough, they can be of several other conditions as well – bipolar disorder or PTSD.
