Dear Nikolas,

A variety of issues could contribute to your mother's moodiness. Is she dealing with chronic pain or a serious illness? Is she under extreme stress? She could be depressed, anxious or suffering from another major mental illness, all of which are rooted in biology and can be treated. Encourage her to see a doctor. First, she needs a complete physical that will include an open and honest discussion of her moods, happiness and anger issues. Good Luck.
