I had a black dog, his name was depression
Depression is a common, but serious medical condition caused by disruptions of the brain’s chemical and electrical messaging systems. 10% of adults in the United States will suffer from a depressive episode in their lifetime. In any year, that means about 14 million will be affected.
While many effective treatments are available, including antidepressant medications and psychotherapy, almost 30% of patients will not benefit significantly. Also, many people cannot tolerate the side effects of antidepressant medication, which include sedation, jitteriness, nausea, weight gain, and sexual dysfunction.
