B-D, or "Bipolar Disorder," is a mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). These mood changes can affect sleep, energy levels, activity, judgment, and behavior, making it challenging for individuals to maintain a stable daily life. Treatment for B-D often involves a combination of medication, such as mood stabilizers and antidepressants, and psychotherapy. Support from family and friends, along with education about the disorder, can also play a crucial role in managing symptoms and improving the quality of life for those affected by Bipolar Disorder.
