Normalcy isn't always constant.
In December - particularly the approach to Christmas - many people normally experience increased feelings of being overwhelmed, anxious, sad and more.
But how do you know if the heightened feelings are normal, seasonal sensations or indicators of a more serious disorder?
That question is addressed by Dr. Laurel Kramer, a local psychologist and counselor, in an article published in the December issue of Active Life, included in Monday's News Tribune.
"Depression increases with the holiday season," she advises, acknowledging the increased stress of too many things to do in too little time, the financial strain of buying presents and/or hosting parties, attending gatherings you'd rather avoid and experiencing grief from the loss of a loved one.
Another factor is Seasonal Affective Disorder (SAD) which refers to the winter gloom, cold and extended darkness that can sap energy and increase moodiness.
"Depression," according to the Mayo Clinic website, "ranges in seriousness from mild, temporary episodes of sadness to severe, persistent depression."
Kramer offers three tips for dealing with the holiday blues.
Keep it simple for you. Choose the events and activities you want to attend and the people you want to spend time with. Downsize your "to do" list.
Take mini-breaks and do it often. Exercise, stretching and breathing techniques are helpful.
Allow the spirit of a deceased loved one to be part of your holiday festivities. Share those good memories with others.
Kramer advises people who are suffering persistent, severe depression to see a health care professional immediately.
A measure of holiday blues is normal this time of year, but clinical depression, like any medical disorder, requires timely treatment.
