Bipolar disorder and depression are Mood Disorders.
This means that they are both mental health conditions that affect your mood in a chronic way, it is more than just being sad or happy. Depression is chronic (meaning long lasting), persistent, debilitating sadness/misery/despair. It creates extreme low mood. Bipolar disorder is a mixture of depression and mania.
