Someone with bipolar disorder can sometimes feel very sad but also full of energy. The surest sign of a phase of depression is that you feel down for a long time -- usually at least 2 weeks. You might have these episodes rarely or several times a year. The most important step you can take is to start and stay on a bipolar treatment plan. Most include a mix of medicine and talk therapy.

Your doctor or therapist may be able to help you schedule absences from work if you need them. Ask a family member of friend for support. They can help you keep up with your appointments and medications.

You can have a few bouts of depression before you have a manic phase. But over time, you'll notice things that cause changes in your mood and warning signs that depression could be setting in. When you catch those symptoms early, you can often avoid major depression. Keep a mood chart to track how you feel, your treatments, sleep, and other activities. Take note of times when you feel stressed -- maybe when you're with certain people or in a specific place. The first signs of depression could be that you feel tired and can't sleep. Short periods of depression can be a sign that a severe phase is coming. The people around you can help you recognize patterns, too. Ask your family and mental health professional to watch for changes in your behavior that signal an oncoming issue. They may be able to notice things that you don't. Even when you feel great, make sure to keep up with your treatment -- it can prevent a relapse of depression. Eat a healthy diet, exercise, and try new ways to ease stress and manage your moods: Join a support group, take up a hobby, or practice relaxation methods like meditation, yoga, or massage.
