Based on your history and the investigations already done, this picture fits very strongly with anxiety-related autonomic overactivity (stress response / panic spectrum disorder) rather than an undiagnosed heart or ear disease.
Key points supporting this:
• Trigger: Severe emotional stress (both parents seriously ill within 15 days) — a classic precipitating factor
• Cardiac work-up normal: ECG, 2D Echo, cardiologist opinion → rules out structural heart disease
• Symptoms fluctuate with medication: Beta-blockers and clonazepam control symptoms → suggests functional (nervous system–driven) cause
• Tinnitus onset after prolonged stress: Very common in anxiety due to heightened central auditory sensitivity
• Persistence despite reassurance: Anxiety disorders often persist even when tests are normal
Importantly:
Next Steps
1. Stop cycling on/off medicines
• Taking beta-blockers or clonazepam intermittently causes rebound symptoms
• Medicines must be taken regularly and tapered properly, not skipped
2. Consult a Psychiatrist (not just GP/ENT/Cardio)
• For proper diagnosis:
• Generalized Anxiety Disorder
• Panic disorder
• Stress-related autonomic dysfunction
• Psychiatrist can:
• Optimize medication (SSRIs/SNRIs if needed)
• Reduce dependence on clonazepam over time
3. Rule out only if clinically indicated (not repeatedly)
Consider once if not already done:
• Serum
electrolytes (Na, K, Mg)
•
Vitamin B12
•
Ferritin / Iron studies
(Deficiencies can worsen anxiety & tinnitus)
4. ENT follow-up
• Tinnitus often persists weeks to months
• Steroids help only if inflammatory; anxiety-related tinnitus improves with stress control
Health Tips
• Do not google symptoms — it significantly worsens tinnitus and palpitations
• Limit:
• Caffeine
• Nicotine
• Energy drinks
• Start daily regulation practices:
• 30 minutes walking
• Slow breathing (4–6 breaths/min)
• Fixed sleep timing
• Avoid silence for tinnitus — use low background sound
• Understand this clearly:
If heart disease were present, symptoms would worsen despite medicines — not disappear with reassurance or clonazepam.
✔ Your symptoms are real
✔ Your organs are structurally normal
✔ The problem is most likely stress-induced autonomic nervous system overdrive (anxiety spectrum)
✔ The right specialist now is a psychiatrist, not another cardiologist or ENT
If you want, I can:
• Explain why tinnitus happens in anxiety
• Help you understand which medicines are safe long-term
• Share non-drug techniques to calm heart rate permanently
