What you’re describing is very likely related to blood
sugar fluctuations, not a personality issue.
Pastries typically contain:
• Refined sugar
• Refined flour
• High glycemic load
This causes:
1. Rapid blood sugar spike
2. Sudden insulin surge
3. Blood sugar crash
That “crash” phase can cause:
• Irritability
• Anxiety
• Frustration
• Overthinking
• Mood swings
This is sometimes called reactive hypoglycemia or a sugar crash response.
At 22 years, this is much more likely metabolic/mood related rather than psychiatric.
The fact that:
✔ Symptoms stop when you avoid pastries
✔ Mood normalizes in 3–5 days
Strongly supports sugar-triggered mood dysregulation.
Also, high sugar intake can temporarily increase inflammation and cortisol, which can worsen anxiety thinking patterns.
Next Steps
✔ Avoid refined
sugar for 2–3 weeks completely
✔ Observe mood stability
✔ Eat pastries only after protein-rich meals (never empty stomach)
✔ Consider checking:
• Fasting glucose
•
HbA1c
• Fasting insulin (if possible)
If mood swings happen even without sugar, then psychological factors should be evaluated.
But right now, your pattern looks dietary-triggered.
Health Tips
✔ Replace pastries with dark chocolate (70%+) occasionally
✔ Add protein + healthy fats to meals
✔ Sleep 7–8 hours
✔ Reduce caffeine
✔ Exercise regularly (improves insulin sensitivity)
Your brain is highly sensitive to glucose swings — this is common and manageable.
If you’d like, tell me:
• Your weight
• Family history of
diabetes
• Whether you feel sleepy after sweets
I can assess whether this is simple
sugar sensitivity or early insulin resistance.
