Question about higher numbers today

My fasting and after lunch numbers were both 87. After breakfast 141 and after dinner 151. These were the highest reads I’ve had ever. That said, I found out awful, shocking news about a family member today and haven’t felt this much stress and sadness in years. Could that have played a role in my numbers? I felt sick to my stomach all day but forced myself to eat because of my damn blood sugar. But I ate the exact same things today as I did yesterday and yesterday’s numbers were all below 100. Help? 😔
