Recently, I started a new job. I went to the toilet about 3 times in the morning before I left out. This had never happened to me before. I guess it was nervousness.
Yes.
When I first had to get up and talk to a huge amount of people.
It did get better over time, but it is not easy to fix.
You really have to be totally in control of your mind, and then! you win yaaaaa :)
