Commonly Misdiagnosed Mental Health Disorders: Why the Right Diagnosis Changes Everything

You’ve been to therapy. You’ve tried medications. You’ve done “everything right”—but something still feels off.
Maybe your antidepressant helps for a few weeks, then stops working. Maybe anxiety meds make you feel numb or irritable. Maybe you’ve been told it’s “just stress,” but deep down, you know it’s more than that.
You’re not alone—and you might not be wrong. Mental health misdiagnosis is far more common than most people realize.
At Favor Mental Health, we’ve spent over 17 years helping Maryland residents uncover what’s really behind their symptoms. Because the wrong label doesn’t just delay healing—it changes the entire trajectory of treatment.
The Hidden Crisis: Why Mental Health Misdiagnosis Happens
Unlike physical medicine, there’s no blood test for depression or brain scan for anxiety. Diagnoses depend on reported symptoms, clinical observation, and context—which makes mental health incredibly nuanced.
Even experienced providers can mistake one disorder for another when:
Symptoms overlap across multiple conditions
Patients minimize or misinterpret their experiences
Coexisting disorders (e.g., anxiety + ADHD) blur the clinical picture
Cultural or gender biases influence how symptoms are perceived
Medication side effects mimic or mask other conditions
The result? A treatment plan that targets the wrong root cause—leading to frustration, side effects, or emotional stagnation.
Depression, Anxiety, and ADHD: The Big Three Misdiagnoses
These three disorders often look alike on the surface—but they function very differently beneath it.
Condition | Core Symptom | Often Misdiagnosed As | Key Differentiator |
Depression | Low mood, fatigue, loss of interest | ADHD or chronic stress | Symptoms persist even during restful periods |
Anxiety | Restlessness, racing thoughts, physical tension | ADHD or OCD | Worry is future-oriented, not distraction-based |
ADHD (Adult) | Inattention, forgetfulness, emotional dysregulation | Depression or anxiety | Onset in childhood, worsens with stress but always present |
Example:
A Maryland professional comes in feeling “exhausted and unfocused.” She’s treated for depression for six months, but nothing changes. After a detailed evaluation, we discover ADHD combined type—with anxiety as a secondary symptom. Once treated properly, her focus, motivation, and mood return.
Bipolar Disorder vs. Depression: The Subtle Distinction That Matters
Nearly 40% of people with bipolar disorder are first misdiagnosed with depression. The reason? They seek help during the “low” phase—and may not recall or recognize hypomanic episodes.
The Consequences
If bipolar disorder is treated as unipolar depression, antidepressants can trigger mania, rapid cycling, or emotional instability.
At Favor Mental Health, our diagnostic process includes:
Detailed mood timeline mapping
Family history review (bipolar often runs genetically)
Sleep and energy pattern analysis
Collateral input from partners or family when appropriate
This helps us ensure treatment enhances stability—not volatility.
PTSD vs. Borderline Personality Disorder (BPD)
Both conditions involve emotional dysregulation, trust difficulties, and fear of abandonment—but the underlying mechanism differs.
PTSD/Complex Trauma | Borderline Personality Disorder (BPD) | |
Core trigger | Past trauma re-experienced | Ongoing fear of rejection |
Emotional pattern | Flashbacks, hypervigilance | Intense, rapidly shifting moods |
Self-image | Guilt, shame tied to events | Chronic instability in self-identity |
Treatment focus | Trauma reprocessing (e.g., EMDR) | Emotion regulation and relational therapy (e.g., DBT) |
A misdiagnosis here can be devastating—leading to stigma, inappropriate medication, and missed trauma healing opportunities.
Physical Conditions That Mimic Mental Illness
Sometimes, what looks like a mental disorder has medical roots.
Physical Condition | Common Misdiagnosis | Underlying Issue |
Thyroid imbalance | Depression or anxiety | Hormonal dysregulation affecting mood |
Sleep apnea | ADHD or depression | Oxygen deprivation and fatigue |
Vitamin B12 deficiency | Cognitive decline, low mood | Nutritional deficiency |
Insulin resistance | Fatigue, irritability | Blood sugar fluctuations impacting neurotransmitters |
PCOS | Depression, anxiety | Hormonal and metabolic imbalance |
This is why Favor Mental Health integrates medical and psychiatric evaluation—to ensure the diagnosis matches the biology.
The Emotional Toll of Misdiagnosis
When you’re treated for the wrong condition, you start to doubt yourself:
“Why can’t I just get better?”“Maybe I’m not trying hard enough.”“What’s wrong with me?”
But it’s not about willpower—it’s about clarity. Misdiagnosis can:
Worsen symptoms through mismatched medications
Erode self-esteem and hope
Delay recovery for years
Create distrust in healthcare
Reframing that experience begins with finding a team that listens, investigates, and validates.

Has your provider ruled out medical causes?
