For me it is Sad, Seasonal affective disorder. As a child I remember looking out the window as twilight is approaching and would feel an unexplainable dread. Fear of something I cannot explain. As a child and young adult when the leaves fall from the trees and all that is left are bare branches, I want to hibernate and wake up in spring. I have learned several things abut SAD. In the elderly, it is sometimes known as Sundowning. The time of day that nursing homes general start handing our meds to keep the agitation or fear. They also move the patients close to the nurses stations to monitor them. I got so depressed after a surgery in the summer a few years ago because I couldn't walk on my leg. Dr. tried a tranquilizer and I can't handle them. I thought about the fact that I was inside a lot, nt getting any sun on my face, or body. I did 2 things. I drastically upped my vitamin D, which is what we get from the sun. And I try to get at least 15 minutes a day in the sun. This has helped immensely The Ott light I have also helps as it has a light that replicates sunlight. It helps to find something to do near twilight, put on all your lights. Dont sit in the dark. Distract yourself until it is completely dark. Im ok once it is fully dark. I liken that to being cozy and safe within my house. I also look at the long winter as a time to cocoon, to reflect inwardly. Im quieter in winter. Counting the days until spring comes and rebirth of everything.
