Why is it harder to find veins for injection on someone who’s feeling nervous about it ?

I was given an injection with a baby needle on my elbow pit. The nurse had to switch veins 4 times (twice in left arm, twice in right arm) and still didn’t manage to give me the injection. I was told it was because I felt nervous so it made my veins “disappeared”. How is that possible ?

Generally when you’re stressed your veins get larger.. maybe she was projecting?

“High stress levels
Increased stress levels can cause vascularity due to higher levels of the stress hormone cortisol. Another hormone called aldosterone can cause water and sodium retention along with increased blood pressure. This can lead to vein swelling.”
