Everyone can have ups and downs. What makes bipolar disorder unique is the extremes of the up and down cycle and the length of the up or down swing. Depression can be mild or debilitating to the point of not being able to perform daily activities and can lead to suicide to find a way out of the hopelessness. The manic side of the disorder is extreme as well and can result in staying awake for days, irritable moods, raging, out of control spending, and many other behaviors. Your mother has bipolar disorder so I assume you have witnessed some of the mood swings and behaviors that accompany the disorder. There are cognitive problems that are common to the disorder as well. Bipolar disorder is genetic. This does not necessarily mean you will develop the disorder. If you think your moods are not within the realm of normalcy then you should see a psychiatrist. You may be experiencing normal ups and downs in life but if you think there is more to it then I urge you to see a psychiatrist. Early intervention and treatment yield the best outcomes. All the best.
