Nearly 19 percent of American adults struggle with an anxiety disorder and 5 to 8 percent deal with depression in a given year, and nearly half of those affected don't get the help they need. Women are at least two times as likely as men to experience these conditions. Woman's Day asked experts to outline the symptoms you may not recognize, and offer a prevention plan.

SYMPTOMS:• Lack of emotion can be a sign a sign of depression. You may feel flat, apathetic or too sad to cry.• Excessive worrying gets in the way of daily functioning may be a sign of generalized anxiety disorder.• Trouble focusing that continues without an apparent cause could signal depression.• Chronic aches and pains with no clear cause. There may be a chicken-and-egg element at work, but can reveal itself physically.

PREVENTION:• Exercise: Any activity, even if it's just 10 minutes of walking can stimulate the release of mood boosting brain chemicals.• Sleep: Studies suggest that chronic sleep-loss tends to desensitize your brain of feel good neurotransmitters such as serotonin.• Cultivate Social Ties: Friendships can help buffer anxiety and depression. Nurture them by picking something you enjoy and making it social: Take a pottery class or sign up to do volunteer work, for example.• Try Not to Ruminate: Instead of stewing about a problem, set aside a time to think about what happened and why you're upset, and postpone worrying until this time.• Manage Stress: We all have stress, but how you cope is key. Don't take too much on, and be sure to include some relaxation in your regular schedule.
