You are not alone. More than 20% of Americans will experience an episode of major depression in their lifetime, yet less than one-third will receive treatment to help overcome the illness.
Your depression was diagnosed months ago, and working with your doctor, you began treatment with a antidepressant medicine. Perhaps you and your doctor may have also worked out a therapy program and discussed "lifestyle" changes. These may include a healthier diet, exercise, regularly scheduled activities that are pleasant for you, and learning to think positively.
Many of the early symptoms of your disease, such as problems sleeping, may have disappeared. Things that used to seem insurmountable now seem manageable. Some of the feelings that used to keep you isolated and stopped you from doing the things you liked to do are becoming a thing of the past. You may be exercising more and feeling physically better ...with fewer aches and pains... and more energy.
People you are close to - your family, coworkers, and friends - have probably noticed the change. You may still have some symptoms... and you may have a way to go to reach complete recovery. But you're more involved with life and you've probably noticed the change yourself.
