People with bipolar disorder may experience periods of elevated mood and energy, known as manic episodes, during which they may feel excessively happy, energetic, and irritable. They may also have racing thoughts, take on more activities than they can handle, and make impulsive decisions.

On the other hand, people with bipolar disorder may also experience periods of low mood, known as depressive episodes, during which they may feel sad, hopeless, and lose interest in activities they once enjoyed. They may also have difficulty concentrating, experience changes in appetite and sleep, and have low energy.

Bipolar disorder can be a severe and debilitating condition, but it is treatable. Treatment may include therapy, medication, or a combination of both. Therapy, such as cognitive-behavioral therapy, can help individuals learn coping skills and techniques for managing their mood swings.

 Medication, such as mood stabilizers and antipsychotics, may be used to regulate neurotransmitter levels and help with mood stabilization.

It is important to seek treatment for bipolar disorder as it can significantly impact a person's quality of life and overall well-being. With proper treatment, individuals with this disorder can learn to manage their mood swings and live fulfilling lives.
