Most Addicts Aren’t “Just Addicts”, They’re Mentally Unwell Too
When families talk about addiction, they focus almost entirely on the drinking or the drugs. They fixate on the chaos, the lies, the emotional exhaustion, the broken promises, the stolen money, the sleepless nights and the fear of what will happen next. What almost nobody talks about is the mental state behind the behaviour. The anxiety. The trauma. The depression. The bipolar mood swings. The hallucinations. The emotional instability that made substances feel like the only way to breathe. People still separate “mental illness” and “addiction” as if they are two different categories of human struggle. They aren’t. They feed each other. They intensify each other. And until you address both together, you fix neither.
Dual diagnosis isn’t rare, it’s the rule. Half of all people with addiction meet criteria for a mental illness, whether diagnosed or not. They aren’t weak or dramatic. They’re overwhelmed. They’re untreated. They’re drowning emotionally and using substances to stay afloat. This is the part families never see, because addicts become experts at hiding their pain. The denial around co-occurring disorders is not just harmful, it’s deadly.
Self-Medication Is Survival (Until It Becomes the Trap That Kills You)
People don’t wake up one day and decide to destroy their lives. Substance use almost always begins as emotional first aid. Someone with untreated anxiety discovers alcohol quiets the panic. Someone with trauma realises cocaine temporarily makes them feel alive again. Someone with depression finds opioids soften the unbearable heaviness. For a moment, they feel normal, or at least numb. The problem is that temporary relief comes at a cost the brain is not built to sustain.
As tolerance builds, substances stop helping and start hurting. What once felt like a solution becomes the very thing making the symptoms worse. Anxiety becomes panic. Depression deepens. Memories of trauma sharpen. Mood swings intensify. Sleep deteriorates. The person is now caught in a trap, they use to feel better, but the use is the reason they feel worse. This is the cycle families misinterpret as selfishness or recklessness. It’s neither. It’s survival that spiralled into self-destruction.
The Most Dangerous Diagnosis
Dual diagnosis is often missed because its symptoms overlap and disguise one another. Substance use can mimic mental illness. Mental illness can mimic substance use. A person may appear manic because of cocaine when in reality they have bipolar disorder. Someone may appear depressed because of withdrawal when the depression existed long before the addiction. Clinicians often misdiagnose because they are seeing symptoms through the fog of intoxication or withdrawal.
Families mistake psychiatric symptoms for “bad behaviour,” “attitude problems,” or “manipulation.” Addicts themselves often don’t know what’s going on, they just know they feel wrong inside. The most dangerous point in dual diagnosis is not relapse. It’s misdiagnosis. Treating only the addiction is like putting a plaster on a bullet wound. The untreated mental illness continues driving the behaviour long after the drugs stop.
Almost No One Gets Real Integrated Care
In South Africa, the gap between what people need and what they receive is enormous. Public mental health is underfunded, overloaded and often inaccessible. Addiction services and psychiatric services operate in separate silos, leaving dual diagnosis patients bouncing between two systems that don’t communicate. Many rehabs claim to treat dual diagnosis because it sounds impressive, but without on-site psychiatry, trauma-trained clinicians, medication management and integrated team meetings, they aren’t treating dual diagnosis. They are treating symptoms in isolation.
Families often assume “rehab” equals psychiatric care. It doesn’t. Many addiction centres cannot safely manage bipolar disorder, schizophrenia, PTSD flashbacks, panic disorders or severe depression. Sending someone with these issues to a standard rehab can make everything worse. People with dual diagnosis need clinicians who understand both illnesses deeply, not a counsellor who hopes mood swings will settle after detox.
The Explosion of Anxiety, PTSD and Depression
South Africans carry some of the highest trauma loads globally. Violent crime, domestic violence, gender-based violence, car accidents, poverty, instability and childhood trauma create a psychological environment where mental illness develops quietly and grows aggressively. People don’t use because they’re weak, they use because they’re overwhelmed. Anxiety fuels binge drinking. Trauma fuels cocaine use. Depression fuels opioid abuse. The substances become emotional anaesthetics, until they turn on the person using them.
When these conditions go untreated, even the best rehab program can collapse. Trauma doesn’t disappear when the drug does. Anxiety doesn’t magically regulate itself. Depression doesn’t lift because someone went to meetings. Without psychiatric intervention, coping strategies, medication where appropriate and trauma-informed therapy, addiction treatment is incomplete.
Untreated Mental Illness Guarantees Relapse
This is the part families struggle with the most. They see relapse and think: He didn’t try. She didn’t care enough. He chose the drugs over us. But relapse is rarely a conscious decision. It is usually an emotional overwhelm the person cannot handle sober. Detox removes alcohol or drugs, but it doesn’t remove panic attacks, intrusive memories, hallucinations, mood swings or depressive crashes. When these symptoms hit without treatment, the person reaches for the one tool they know regulates their emotions: substances. This isn’t failure. It’s untreated illness.
Families often misread psychiatric symptoms as manipulation. They punish mood swings. They shame emotional instability. They blame the person for symptoms they cannot control. The tragedy is that many addicts relapse not because treatment failed, but because the mental illness driving the addiction was never addressed.
When Addiction Isn’t the Only Problem
Rehab saves lives, but only if it’s the right kind of rehab. People with dual diagnosis need integrated treatment. Sending someone with bipolar disorder to a standard addiction centre is like sending someone with a broken spine to a chiropractor and hoping it works out. They need psychiatric assessment, medication stabilisation, trauma therapy and addiction-specific counselling delivered by the same team, not different companies or departments.
Sequential treatment, treating addiction first, mental health later, fails because psychiatric symptoms cause relapse during early recovery. Parallel treatment, treating both conditions at the same time but in different silos, fails because communication is fragmented. Only integrated treatment has consistently strong outcomes.
Why Co-Occurring Disorders Are Hidden, Downplayed and Lied About
In South Africa, people will disclose addiction long before they disclose mental illness. Addiction is seen as reckless. Mental illness is seen as weakness. People don’t want to be labelled “crazy.” They don’t want assumptions made about their competence, their reliability, their parenting, their intelligence or their stability. So they hide. They joke. They deflect. They build emotional armour so thick that even the people closest to them can’t see they’re drowning.
Families collude in the silence. They don’t want neighbours to know. They don’t want workplaces to know. They don’t want relatives to judge. This secrecy kills people. It delays treatment. It increases relapse. It prevents early interventions. Shame is the barrier that keeps dual diagnosis patients invisible until they hit crisis.
Trauma Is the Unseen Engine of Most Dual Diagnosis Cases
Trauma is not a side issue. It is often the central issue. Childhood abuse. Rape. Violent crime. Neglect. Emotional abandonment. Repeated loss. These experiences alter the nervous system, creating hypervigilance, emotional reactivity, dissociation, depression, chronic anxiety and sleep disruption, all of which increase addiction risk dramatically.
If treatment doesn’t address trauma, the person is left fighting with the same internal demons that drove them to substances in the first place. Trauma-informed care is not optional. It is essential.
The Mental Health Symptoms People Mistake for “Relapse Behaviour”
Families often punish the wrong things:
- Emotional overwhelm
- Irritability
- Panic attacks
- Mood swings
- Racing thoughts
- Paranoia
- Dissociation
- Intrusive memories
- Depression
- Social withdrawal
These are not signs of selfishness. They are signs of psychiatric distress. If families treat them like behavioural problems, the person spirals further.
“Self-Diagnosis Culture” Keeps People from Real Treatment
There is growing danger in the trend of diagnosing yourself based on TikTok or Instagram. People convince themselves they have ADHD, borderline personality disorder, bipolar disorder or complex trauma without ever seeing a clinician. Self-diagnosis leads to self-medication, which leads to addiction. And once addiction starts, the real illness becomes even harder to diagnose.
Proper assessment is not optional. It is the foundation of recovery.
You Can’t Fix Addiction Without Fixing the Mind Behind It
Dual diagnosis is not an optional add-on. It is the core of most addiction cases. Treat both or treat neither. The message every family needs to hear is simple, this isn’t madness. It isn’t weakness. It isn’t selfishness. It’s illness, and with the right care, it is treatable. Recovery becomes possible the moment we stop separating mental illness from addiction and start treating them as the intertwined crises they are.
