One of the most reassuring things I learned after Peyton died was that grief doesn't just break your heart.
It changes your brain.
Suddenly, I couldn't concentrate. I'd forget why I walked into a room. I'd read the same paragraph three times without remembering a single word.
I thought something was wrong with me.
There wasn't.
Researchers have found that overwhelming loss changes the way different parts of the brain work. The amygdala—our brain's alarm system—becomes more sensitive, always scanning for danger. At the same time, the prefrontal cortex, the part responsible for concentration, planning, and decision-making, doesn't function as efficiently under extreme stress.
That's why you may struggle to focus, forget simple things, or feel mentally exhausted.
The hippocampus, which helps organize memories and place them in time, can also be affected. That's one reason a smell, a song, or a certain date can make it feel as though your loved one died yesterday instead of years ago. Your brain isn't simply remembering the event—it can momentarily experience it as if it's happening again.
Learning this didn't lessen my grief.
But it did lessen my fear.
I wasn't losing my mind.
My brain was doing exactly what brains do after traumatic loss.
Understanding that gave me permission to stop fighting myself and start showing myself the same compassion I would have offered anyone else.
