Mood Swings
Rapid or unpredictable shifts in emotional state, moving between different moods more quickly or intensely than feels typical for you.
Also known as: emotional ups and downs, emotional instability, rapid mood changes, emotional rollercoaster, mood fluctuations
What This Can Look Like
Mood Swings can show up differently in different situations. Here are some common experiences:
“Some people describe feeling fine one moment and then deeply upset the next, sometimes without any clear trigger.”
“This might look like going from energized and optimistic in the morning to feeling hopeless by evening, with the shifts feeling confusing and hard to predict.”
“For example, a minor disappointment might trigger intense sadness that feels overwhelming but then lifts within hours.”

Conditions Where This Can Appear
Important: Experiencing mood swings does not mean you have any particular diagnosis. Many people experience this without having a diagnosable condition. Only a qualified professional can determine if symptoms meet criteria for a specific diagnosis.
Bipolar Disorder
Involves distinct episodes lasting days to weeks, not moment-to-moment shifts within a single day.
Borderline Personality Disorder
Mood shifts tend to be rapid (hours), intense, and often triggered by interpersonal events.
Premenstrual Dysphoric Disorder
Mood swings occur in a predictable pattern related to the menstrual cycle.
Other Possible Causes
Mood Swings can sometimes have non-psychological causes that are worth considering:
- Hormonal fluctuations (menstrual cycle, perimenopause, thyroid)
- Sleep deprivation can destabilize mood
- Blood sugar swings may contribute
- Some medications can affect mood stability
- High stress periods can increase emotional reactivity
- Substance use and withdrawal
If you're experiencing persistent or concerning symptoms, it's always a good idea to talk with a healthcare provider who can help rule out medical causes.
When to Consider Getting Support
While experiencing mood swings doesn't automatically mean you need professional help, there are times when reaching out can be beneficial:
- When mood swings significantly impact relationships or work
- When you notice patterns that concern you
- When the shifts feel uncontrollable
- When accompanied by impulsive behaviors you regret
