Mood Swings and Chronic Illness: Why It Happens and How to Find Emotional Relief Without Shame

Aug 17

It's Not Just in Your Head—It's in Your Biology

If you're living with a chronic illness or autoimmune condition, you already know it’s not just the physical symptoms that wear you down—it’s the emotional rollercoaster, too. One day you're okay, the next you're in tears or snapping at someone you love. Then comes the guilt. The shame. The inner dialogue that whispers, “Why can’t I just get it together?”

Here’s the truth I want you to hear loud and clear:
You are not broken. Mood swings are not a personality flaw. They’re biological signals—honest messages from your nervous system, your hormones, and your immune system.

Your emotional landscape is not separate from your body—it is your body.

In this post, I’ll show you what’s really happening inside your system when mood swings show up—and how to respond with curiosity and compassion, not criticism.

Why Mood Swings Happen in Chronic Illness

As a clinical psychotherapist and somatic practitioner, I’ve seen how chronic illness impacts emotional regulation on every level. When your body is chronically inflamed, hormonally imbalanced,or in a prolonged stress state, your brain chemistry becomes harder to stabilize.

Here’s what’s actually happening:

Cortisol dysregulation: Chronic stress overactivates your adrenal system, disrupting your baseline cortisol levels. The result? Mood swings, poor sleep, heightened anxiety, and difficulty adapting to change.
Neurotransmitter imbalance: Chronic illness often depletes serotonin, dopamine, and GABA—neurochemicals that stabilize mood. This leads to mood swings, irritability, anxiety, and even depressive dips.
Inflammation and the brain: Pro-inflammatory cytokines (tiny immune messengers) can cross the blood-brain barrier and disrupt brain function, leading to emotional reactivity, brain fog, and reduced emotional resilience.
Hormonal shifts (especially in cyclical bodies): Estrogen, progesterone, and testosterone are deeply tied to emotional regulation. For many with chronic illness, hormonal transitions like menstruation, ovulation, perimenopause, or postpartum can intensify symptoms and destabilize mood.

So when you feel emotionally volatile for “no reason,” let this be your reminder::
There is a reason. Your body is speaking in the language of emotion.

The Nervous System’s Role in Emotional Overwhelm

Let’s bring in somatic science: your autonomic nervous system is your emotional command center. It’s responsible for how you perceive threat, manage energy, and recover from stress.

When you're living with chronic illness, your system is often stuck in a state of:

Hypervigilance (fight/flight): everything feels urgent, overwhelming, or overstimulating
Shutdown (freeze/dissociate): emotional numbness, fatigue, or disconnection

This can look like:

Crying easily—or not at all
Feeling “on edge” or emotionally flooded by small things
Losing patience or withdrawing from people
Struggling to calm down or regulate after conflict

This is not a failure of willpower or a mindset issue.
It’s a state shift in your autonomic nervous system, often triggered by inflammation, pain, or unresolved trauma patterns.

Breaking Free from Shame Around Mood

If you’ve ever been told:

“You’re just moody.”
“You’re too sensitive.”
“You need to toughen up.”

I want you to replace that script with this:

Your emotions are data, not drama.
Your mood swings are messages, not misbehavior.
Sensitivity is not weakness—it’s nervous system intelligence.

Shame thrives in silence and self-judgment. But understanding connects. When you begin to view your emotions as biologically rooted, you create space for compassion and healing.

How to Hold Your Emotions with Compassion

You don’t have to suppress your feelings—or get stuck in them. These trauma-informed, somatically groundedpractices are designed to help you regulate in real time.

1. Name it to tame it

Label your emotional state: “I feel anxious,” “I’m overwhelmed,” “I’m irritable.”
Language engages the prefrontal cortex, helping your brain settle.

2. Ground through the body

Return to safety through the senses:

Breathe into your belly
Gently rock side to side
Place a cold object in your hands
Press your feet into the floor with awareness

3. Create emotional boundaries

Your nervous system has limits. Respect them.
Step away from draining conversations or overstimulating environments when needed.

4. Track your cycle

If you menstruate, notice how your mood and energy shift throughout your cycle. Many people with chronic illness notice their emotional resilience drops during the luteal or menstrual phase.
Your emotional needs aren’t the same every day—and that’s okay.

5. Practice compassionate self-talk

Try affirmations like:

“It’s okay to feel this way.”
“This is a signal, not a setback.”
“My body is asking for gentleness.”

These practices—and many more—are part of The Flare Care Protocol, my comprehensive system for emotional regulation, cycle syncing, and nervous system support.
