Trigger a change in body temperature to the point you get flagged as having a fever of 100 degrees?

I suffer from severe health anxiety and have been a ball of stress and anxious this entire week.

Got flagged at 100 degrees with an ear thermometer but I don’t feel like I have a fever.

Well after that, every damn day I have been feeling my checks and I am convinced I have a fever now. My breath even feels warm. But I am so concerned about the fever now.

Anyone that suffers from anxiety and stress have drastic changes in their body temperature all day? And for a couple of days?
