What you are experiencing is very real and very distressing, but based on your description, this sounds like a stress–migraine–anxiety cycle, not a life-threatening heart or brain condition.
Extreme stress can:
• Worsen migraine
• Trigger palpitations, fast heartbeat, chest tightness
• Create a strong fear of dying, even when the body is not actually failing
This does not mean you are weak or that something catastrophic is about to happen. It means your nervous system is overwhelmed and stuck in “alarm mode.”
Importantly: stress and anxiety themselves do NOT cause sudden death, especially in a young parent with no known heart disease.
Your fear is amplified because you love your child and feel responsible — that is a protective instinct, not a danger signal.
Next Steps
These are the most important actions now:
1. Rule out danger once (not repeatedly)
• If not done recently: ECG + basic labs (to reassure your mind)
• Once normal → stop re-checking vitals daily (this fuels anxiety)
2. Target the root: nervous system overload
• Migraine prevention + anxiety regulation together works best
• Short-term support (doctor-guided):
• Migraine preventive or abortive meds
• Low-dose anti-anxiety support if symptoms are frequent
• This does not mean lifelong medication
3. Create a safety plan
• One trusted doctor (not many opinions)
• One clear plan for migraine/palpitations episodes
• Knowing what to do reduces fear dramatically
Health Tips
• When palpitations start:
• Sit down, slow breathing (4 sec in – 6 sec out)
• Say to yourself: “This is uncomfortable, not dangerous.”
• Migraine + anxiety is very common in mothers under stress
• Your baby needs you alive and functional, not silent suffering
• Getting help is protecting your child, not neglecting her
