Perimenopause: The Emotional Side Nobody Warned You About
Anxiety out of nowhere. Rage you don’t recognize. Wide awake at 3am. For a lot of women, perimenopause shows up in the mind before anyone calls it perimenopause.

Quick answerPerimenopause is the transition before menopause, when estrogen rises and falls unpredictably. It usually begins sometime in your 40s, though some women notice changes in their 30s, and it can last several years. For many women, the changes that hit hardest are emotional: anxiety, irritability or rage, low mood, poor sleep and brain fog.
My Approach
The Mental Side of a Physical Change
I’m not a doctor, and nothing here replaces medical care. Your doctor can help with what’s happening in your body. I help with what’s happening in your mind: your nervous system, your emotions and your relationships.
I know this one from the inside. My own perimenopause rage began at 38, and for two years I didn’t recognize myself. Read my menopause rage story.
Start Here
Start With What You’re Feeling
Mood and emotions
- Perimenopause anxiety: dread, a racing heart and worry that arrives out of nowhere
- Perimenopause rage: sudden anger and irritability, and why it lands on the people you love
- Mood swings and depression: how to tell them apart, and when to get help right away
Body and energy
- Perimenopause insomnia: waking at 3am and not getting back to sleep
- Perimenopause fatigue: a tiredness that sleep doesn’t fix
- Brain fog, memory and ADHD: losing words, losing focus
- Cortisol and stress: what’s real about “cortisol belly,” and what helps
Life and relationships
- Early perimenopause: the signs in your late 30s and early 40s
- Menopause and relationships: anger, intimacy and staying connected
- Yoga for menopause: gentle poses, yoga nidra and when it isn’t enough
What Helps
Five Things That Help, Starting Today
- Name it. “This is my hormones talking, not my whole self.” Naming it buys you a second before you react.
- Breathe out longer than you breathe in. In for four, out for six, five times. A longer exhale helps your body stand down. More in breathing exercises.
- Protect your sleep. If 3am waking is wearing you down, try my 26-minute yoga nidra for sleep.
- Tell the people close to you. “I’m going through something, and it isn’t about you” changes how a hard day lands at home.
- Bring it to your doctor. Many perimenopause symptoms have medical treatments, and you deserve to be heard.
If your body feels stuck on high alert, how to regulate your nervous system goes deeper.

When to Get Help
When to See a Doctor
See a clinician about any new or worsening symptom, especially low mood that won’t lift, a racing or irregular heartbeat, or very heavy or irregular bleeding. If you’re thinking about hurting yourself, call or text 988, the Suicide & Crisis Lifeline in the US. If you’re in immediate danger, call 911. Coaching is not therapy or medical care.

Frequently Asked Questions
Perimenopause FAQ
What is perimenopause?
Perimenopause is the transition leading up to menopause, when estrogen rises and falls unpredictably and periods start to change. Once you’ve gone 12 months in a row without a period, you’ve reached menopause and perimenopause is over.
What age does perimenopause start?
It usually begins sometime in your 40s, though some women notice changes in their 30s and others not until their 50s. It can last several years.
What are the emotional symptoms of perimenopause?
Commonly reported emotional changes include anxiety, irritability or rage, mood swings, low mood and a higher risk of depression, along with brain fog and poor sleep. Women who have had depression, anxiety or strong premenstrual mood changes before are more likely to notice mood changes in perimenopause.
Can perimenopause cause anxiety and rage even if my periods are regular?
It can. Estrogen rises and falls unpredictably in perimenopause, and the first changes to your cycle can be small, like a week’s difference in length. That’s one reason early perimenopause is often missed.
When should I see a doctor?
See a clinician about any new or worsening symptom, especially low mood that won’t lift, a racing or irregular heartbeat, or very heavy or irregular bleeding. If you’re in crisis in the US, call or text 988.
