LOSS OF APPETITE:
If any emotion develops excessively, appetite suppresses eventually. During an immense of happiness, one does not desire to eat. A similar thing happens when a person is sad. However, appetite loss due to ecstasy is short-term, and that owing to depression is quite long. Hence, if you or anyone around you has started skipping their meals, has reduced their meal size, prefers other activities over eating, or have stopped enjoying meals, it might be an indication of depression. All you need to do is to stop at that very moment of realization and figure out the actual cause of appetite loss.
