When Friendships Fray: Chronic Illness & the Nervous System

In my counselling practice, one of the most tender and recurring themes emerging from clients living with chronic illness is this: the heartbreak of friendships quietly dissolving—or painfully erupting—while navigating an invisible illness.

For those living with conditions like chronic fatigue, ME/CFS, long COVID, or fibromyalgia, the physical symptoms—like brain fog, post-exertional malaise, and immune or cardiac flares—are only part of the struggle. The social nervous system suffers too. Relationships often fracture, leaving clients feeling confused, hurt, isolated, and dysregulated.

And as a somatic therapist who works through the lens of polyvagal theory (thank you, Deb Dana), I see this not just as relational grief—but also as a profound nervous system injury.

Our nervous systems are wired for connection. When illness limits our capacity—whether physically, mentally, emotionally or energetically—our ability to co-regulate with others changes. And when friends fail to meet us with compassion or presence, it sends powerful signals to the body: “I am not safe. I am not seen. I am alone.”

Clients often describe three distinct patterns in friendships that have deeply affected their health and healing journey:

Sometimes, the drifting is subtle—friends no longer respond to messages, special dates go unnoticed, or life events like motherhood or new jobs consume their focus.

And while it’s not deliberately cruel, the silence feels like abandonment.

“These were my core people. We lived together at boarding school. I’ve always shown up for them. Why haven’t they shown up for me—especially when I was in hospital?”
This distancing sends a clear message to the nervous system: social disconnection = danger. And for someone already dealing with health collapse, the added relational loss can compound their exhaustion.

Their ventral vagal state—the place where we feel safely connected—is shaken. Many clients enter a state of sympathetic overdrive (anxious hypervigilance) or drop into dorsal shutdown (numbness, withdrawal).

Then there are friendships that were always conditional—but chronic illness finally brought the toxicity into sharp relief.

“I gave everything I had—often to my own detriment. She took, and took, and when I finally set a boundary, I was met with blame, emotional manipulation, and cruelty.”
When the nervous system is already inflamed and struggling, a single text, voice message, or emotionally laced encounter can trigger neurocardiac symptoms, immune flare-ups, and weeks—or months—of nervous system fallout.

This isn’t just emotional pain. It’s a biological threat response.

“After receiving her message, my heart rate spiked, my smart watch sent me a health alert, and I needed a walking stick just to make it to the toilet.”
Toxic relationships send the body into repeated cycles of threat, collapse, and survival mode. And unlike acute stress, chronic relational stress erodes the body's capacity to repair.

There are also beautiful, well-intentioned friends who reach out—but whose words unintentionally hurt.

“I told a friend what the immunologist said about learning to boil an egg being an achievement... and she replied that she boils 50 eggs a week and agrees it’s a great accomplishment.”
This isn’t malicious. But it highlights the massive gulf between the client's internal world and their friend's reality. When someone is surviving on micro-moments of energy, a misplaced comment can tip the nervous system into sympathetic activation or dorsal collapse.

Even a kind visit can take weeks of recovery. It becomes a high-cost experience—leading many to conclude that isolation feels safer.

“Texting is best for me, but not for them. So I withdraw further. And feel even more alone.”
 

This territory is painful. Messy. And layered with grief.

In our work together, clients often bring journals, reflections, and broken pieces of trust into our counselling space. We slowly begin to sort the debris—gently, with compassion—and invite the nervous system to reorient toward safety again.

We don’t try to “fix” the friendship loss. Instead, we ask:

• What does your nervous system need right now?
• Where does safety live in your body today?
• What kind of relational nourishment do you long for?
• What boundaries are your body asking you to uphold—without guilt?
   

As Deb Dana teaches, “story follows state.” When the nervous system is in a regulated, ventral space, our stories soften. Meaning returns. Trust can begin to rebuild—not necessarily in the old friendships, but in ourselves.

If you’re navigating chronic illness and the loss of connection, please know:

💛 You are not weak for needing rest.
💛 You are not oversensitive for being affected.
💛 You are not broken for being impacted so deeply by the words—or silence—of others.

Your nervous system is doing its best to keep you safe. And in the absence of understanding from others, you can offer yourself the co-regulation and kindness you deserve.

You are allowed to outgrow toxic dynamics.
You are allowed to grieve the absence of care.
You are allowed to protect your energy - and still long for connection.

And in time, may the friendships that remain (or emerge) be the ones that honour your capacity, your truth, and your sacred nervous system.

If you’re living with chronic illness and navigating relational rupture, you’re welcome in this space. At Nourish Your Wellbeing, I offer counselling support that weaves together nervous system care, self-compassion, and trauma-informed insight. Let’s rebuild from here.
