Depression is more than feeling sad or having a bad day. It can affect your sleep, appetite, energy, and interest in everyday activities, and it is treatable.
Bipolar disorder involves distinct episodes of intense emotion and changes in energy, activity, or sleep, ranging from elevated, manic periods to depressive ones.
A distressing or traumatic event can lead to lasting symptoms like nightmares, anxiety, avoiding reminders, and difficulty in relationships. Effective treatment is available.
