The Hidden Mental Health Toll of Chronic Illness

Mental health conversations often focus on diagnoses like depression or anxiety, but experts say there is another deeply overlooked issue affecting many patients living with chronic illness: medical trauma. According to Bonnie J. Mitchell, DBH, LPCC, clinical director at The Mental Health and Stabilization Center of Sacramento, the ongoing stress of navigating chronic disease can leave lasting emotional and psychological effects that are frequently misunderstood or dismissed.

In an interview with The Educated Patient, Mitchell discusses how chronic conditions can contribute to emotional exhaustion, trauma responses, anxiety, depression and feelings of grief, while also highlighting why validation, support and mental health care are so important for patients and families.

Living with a chronic illness often means managing symptoms, medications,
uncertainty and lifestyle changes every single day. From your perspective, how does that ongoing burden affect a person’s mental health over time?

Bonnie J. Mitchell, DBH, LPCC: Living with a chronic illness is not a sprint; it’s a marathon with no finish line, where the terrain changes without warning. Managing symptoms, medication regimens, lifestyle restrictions and the sheer unpredictability of a condition day in and day out requires an immense amount of cognitive and emotional energy.

Over time, this relentless baseline of stress can lead to what we call allostatic load, the wear and tear on the body and brain caused by chronic stress. Mentally, this manifests as deep exhaustion, often referred to as “health burnout.” When a person must constantly negotiate their body’s limitations, the brain’s threat detection system (the amygdala) remains chronically activated. This persistent state of high alert frequently erodes a person’s psychological resilience, leaving them highly vulnerable to clinical depression and generalized anxiety disorder. It is a structural, chemical response to a prolonged siege, not a personal failing.

Many patients say they feel grief, anxiety, guilt or even isolation after being
diagnosed with a chronic condition. Why are these emotional responses so common, and what do you wish more patients and families understood about the psychological side of chronic illness?

BM: When a person is diagnosed with a chronic condition, they are experiencing a profound loss attached to that label. Grief is an entirely natural response to losing the life they planned, the version of themselves they knew, or the future they envisioned.

Anxiety stems from the loss of predictability and not knowing how they will feel
tomorrow, next week or next year. Guilt often arises because patients feel they are letting down their employers, friends or families due to canceled plans or shifting financial and caregiving dynamics. Isolation occurs because it is incredibly lonely to inhabit a body that functions differently than the bodies of those around you.

What I wish patients and families understood most is that these emotions are not complications of the illness — they are part of the illness. Emotional distress is a physiological and psychological reality of adapting to a major life trauma. Families need to know that validation, rather than toxic positivity or rushed problem-solving, is the most powerful support they can offer.

Chronic illnesses are frequently described as “invisible,” especially conditions like autoimmune diseases, chronic pain disorders, migraine or gastrointestinal conditions. How can feeling misunderstood or dismissed by others impact mental health and self-esteem?

BM: When a condition like fibromyalgia or Crohn’s disease cannot be seen on the outside patients face a secondary trauma: the burden of proof. Having your pain, fatigue or limitations dismissed, minimized or doubted by loved ones, employers or even medical professionals is deeply destabilizing.

This dynamic often forces patients into a harmful cycle of self-doubt and internalized stigma. They begin to ask themselves, “Is it all in my head? Am I just weak?” This erodes self-esteem and creates a profound sense of invalidation. When the world tells you that you look fine, but your lived experience is one of suffering, it creates a fracture in your reality. This sense of being misunderstood can lead patients to socially withdraw to avoid judgment, compounding their isolation and accelerating depressive symptoms.

There is often a strong connection between stress and physical symptoms, where mental health struggles can worsen chronic illness flares and vice versa. Can you explain that relationship and what patients can do to help break that cycle?

BM: The relationship between chronic stress and physical illness is a bidirectional highway, governed largely by the brain-gut axis and the neuroendocrine system. When a patient experiences a physical flare, it triggers psychological stress and anxiety. This mental stress causes the body to release pro-inflammatory cytokines and stress hormones like cortisol and adrenaline. These chemicals increase muscle tension, alter gut motility, heighten pain sensitivity and suppress immune functions and ultimately triggering or worsening a physical flare.

To break this vicious cycle, we must intervene on both sides of the highway:

• Regulate the nervous system: Engaging in daily practices that stimulate the vagus nerve and activate the parasympathetic nervous system (the “rest and digest” mode) is vital. This includes deep diaphragmatic breathing, mindfulness or progressive muscle relaxation.
• Cognitive reframing: Therapy, particularly acceptance and commitment therapy (ACT) or cognitive behavioral therapy (CBT), can help patients change their relationship with their symptoms, reducing the panic response that often exacerbates physical pain.
• Pacing over pushing: Learning the art of pacing helps prevent the “boom-and-bust” cycle, reducing the physical volatility that triggers emotional distress.

During Mental Health Awareness Month, what practical advice would you give patients who may be focused entirely on managing their physical symptoms but have not addressed the emotional toll their condition is taking on them?

BM: To the patients who are fighting so hard for their physical health but find themselves empty on the inside, my advice is this: Your emotional well-being is not a luxury; it is a clinical necessity. You cannot effectively manage a chronic physical condition if the mind steering the ship is neglected and exhausted.
For Mental Health Awareness Month, I challenge you to take these practical steps:

• Expand your care team: If your medical team only consists of specialists for your physical body, it’s time to add a mental health professional. Ideally a health psychologist or therapist specializing in chronic illness.
• Audit your emotional energy: Just as you track your physical symptoms, track your joy and peace. Permit yourself to say no to obligations that drain you, and actively schedule activities that fulfill you, even in small, adapted ways.
• Shift from fighting to partnering: Stop viewing your body as an enemy to be conquered. Try to view it as a wounded partner that needs compassion. Treat yourself with the same gentleness and accommodation you would readily offer a friend dealing with the exact same health challenge.
