How Do I Know If I Have Depression and Anxiety?

Many people experience periods of sadness or worry, but when those feelings become persistent and interfere with daily life, they may indicate clinical depression, an anxiety disorder, or both.

As a PMHNP at East Valley Psychiatric Services in Gilbert, we often help patients sort through overlapping symptoms and decide when to seek evaluation. Here, we take the time to explain common signs, how clinicians diagnose these conditions, and treatment options available in Gilbert and the East Valley.

Depression and Anxiety

Understanding the Basics: What Depression and Anxiety Are

Depression and anxiety are distinct diagnostic categories that frequently occur together. Major depressive disorder primarily involves persistent low mood, loss of interest or pleasure, sleep and appetite changes, low energy, concentration problems, and sometimes suicidal thoughts. Anxiety disorders—such as generalized anxiety disorder, panic disorder, and social anxiety—are marked by excessive worry, heightened physiological arousal, and avoidance behaviors.

Co-occurrence is common: anxious thoughts can worsen depressive symptoms, and depressive withdrawal can increase anxiety about daily functioning. Proper evaluation recognizes both conditions so treatment can address the full clinical picture.

Key Signs That Suggest Clinical Depression

Occasional sadness is normal, but clinical depression is more severe and sustained. Consider professional evaluation when you notice several of the following for most of the day, nearly every day, for two weeks or longer:

  • Persistent sadness, emptiness, or hopelessness
  • Marked loss of interest or pleasure in activities (anhedonia)
  • Significant changes in appetite or weight
  • Insomnia or sleeping too much
  • Low energy or fatigue
  • Difficulty concentrating, making decisions, or remembering
  • Excessive guilt or feelings of worthlessness
  • Recurrent thoughts of death, suicidal ideation, or past attempts

If you have active suicidal thoughts or intent, seek immediate help through emergency services or crisis lines. Safety assessment is a priority in any clinical evaluation.

Key Signs That Suggest an Anxiety Disorder

Anxiety becomes clinically significant when worry is excessive, hard to control, and causes functional impairment. Common indicators include:

  • Persistent, uncontrollable worry about multiple areas of life
  • Restlessness, feeling keyed up, or on edge
  • Muscle tension, headaches, or gastrointestinal upset
  • Rapid heartbeat, sweating, trembling, or shortness of breath
  • Difficulty sleeping because of racing thoughts
  • Avoidance of situations that trigger anxiety

Panic attacks are intense episodes of fear that peak within minutes and include symptoms like chest pain, dizziness, fear of losing control, or fear of dying. Recurrent unexpected panic attacks may indicate panic disorder.

How Depression and Anxiety Overlap

Depression and anxiety share symptoms such as sleep disturbance, concentration problems, and fatigue. Many patients present with mixed symptoms: persistent worry may lead to sleep loss and low energy, while low mood can amplify anxious rumination. Clinicians assess symptom patterns, timing, and severity to determine primary versus secondary diagnoses and to plan integrated treatment.

How Clinicians Diagnose These Conditions

Diagnosis is a clinical process that combines history-taking, standardized screening, and medical evaluation:

  • Clinical interview: A structured conversation about symptom onset, duration, triggers, functional impact, and past treatment.
  • Standardized scales: Tools such as the PHQ-9 for depression, GAD-7 for generalized anxiety, and the Mood Disorder Questionnaire for bipolar screening help quantify symptoms and track progress.
  • Medical review: Basic labs and a medical history rule out medical causes like thyroid dysfunction, vitamin deficiencies, or medication side effects that can mimic mood or anxiety symptoms.
  • Collateral information: When appropriate, input from family or other providers can clarify symptom severity and patterns.
  • Differential diagnosis: Clinicians must distinguish primary mood or anxiety disorders from substance-induced symptoms, medical conditions, bereavement, or personality disorders.

Accurate diagnosis guides treatment: for example, unrecognized bipolar spectrum illness may worsen with antidepressant monotherapy, so identifying mood elevation history is essential.

Treatment Options: What Works

Both depression and anxiety are treatable. Effective care often combines psychotherapy, medication when appropriate, lifestyle interventions, and ongoing monitoring. Treatment plans should be individualized based on diagnosis, symptom severity, prior response to treatments, medical history, and patient preferences.

Psychotherapy

Evidence-based psychotherapies are central to treatment:

  • Cognitive Behavioral Therapy (CBT): CBT targets unhelpful thoughts and behaviors, teaches coping strategies, and includes behavioral activation to reverse withdrawal and inactivity common in depression.
  • Exposure-based therapies: For panic disorder, social anxiety, and specific phobias, graded exposure reduces avoidance and anxiety responses.
  • Interpersonal Therapy (IPT): IPT addresses relationship problems and role transitions that can trigger or maintain depression.
  • Acceptance and Mindfulness approaches: These teach acceptance of internal experiences and reduce struggle with anxious or depressive thoughts.
  • Supportive and motivational approaches: These enhance engagement, build skills, and address ambivalence about change.

Medication

Medications can be essential, especially for moderate to severe symptoms or when psychotherapy alone is insufficient. Common options include:

  • Antidepressants: SSRIs and SNRIs are frequently prescribed for both depression and many anxiety disorders. They can take several weeks to show full benefit.
  • Adjunctive agents: Atypical antipsychotics or other augmentation strategies may be used for treatment-resistant depression under close supervision.
  • Mood stabilizers: Used when bipolar disorder is present or suspected.
  • Short-term anxiolytics: Benzodiazepines or other fast-acting agents may be used briefly for acute anxiety, with caution regarding dependency.

Medication decisions consider past response, side effect profiles, medical interactions, and patient goals. Regular follow-up is crucial to adjust dosing, monitor side effects, and evaluate benefit. For severe or refractory cases, options such as transcranial magnetic stimulation (TMS) or electroconvulsive therapy (ECT) may be considered in coordination with specialists.

Lifestyle and Supportive Measures

Lifestyle changes support symptom reduction and resilience:

  • Consistent sleep hygiene and routines
  • Regular physical activity, which has antidepressant and anxiolytic effects
  • Balanced nutrition and avoiding excessive alcohol or recreational drugs
  • Stress-reduction practices such as mindfulness, breathing exercises, or yoga
  • Social support and engagement to reduce isolation

When to Seek Professional Help

Consider reaching out to a highly-trained clinician if symptoms are persistent, worsening, or interfering with work, relationships, or self-care. Immediate evaluation is warranted for suicidal thoughts, severe functional decline, or inability to care for oneself. Early intervention improves outcomes and can prevent complications such as substance misuse or hospitalization.
