SAD (or Seasonal Affective Disorder) is defined as "A form of depression occurring at certain seasons of the year, especially when the individual has less exposure to sunlight."
I get SAD every January and February. I'm in one SAD period right now. I have no desire for activity, whether it's simply going someplace or doing something. I'd rather stay home lying down on my couch. Even my computer and the Internet hold no curiosity for me.
I eat junk food like it's the last food on earth, just shoving it into my mouth: cookies, candy, etc. and am gaining the corresponding weight. I even have a sun lamp which I put on as soon as I'm in the den - to no avail. I need the real sun.
The Mayo Clinic says that, in order to deal with SAD, I should write down:
All my symptoms (see above)
All my meds (done)
Any major stressors or life changes
Other mental or physical health problems
See your doctor (seeing therapist on a regular basis)
My self esteem is very low normally and SAD puts me into a downward spiral. I get more depressed as I eat bad carbs (You should know better by now!) and gain more weight (You know how to eat properly!)
The only life change I experience is longer and colder days. With fibromyalgia, I have to make sure that I don't get chilled, so I wrap myself in afghans when I get cold. If I run errands, I need to get my car warmed as soon as possible.
Solution? Move to a place where winter isn't so long or accept SAD and deal with its consequences when the sun comes out again. See you all in April!!
