Moodiness can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose moodiness, we could:
How often do you get into a bad mood?
Possible responses:→ Don't know
→ Never/rarely - I am generally balanced/cheerful
→ I usually have a few bad moods each year
→ I am regularly in a bad mood
→ Very often - several times a week on average
