when they take a few drops of my blood for analysis?
Today I did it. At work. And scared [i.e. worried] most of my colleagues. I came out of the room where they took a few drops of my blood for medical analysis (I am new at work and such papers are needed), I didn't know this was going to happen today, I was called for a psychiatric evaluation test and for taking my blood pressure, I came out of the respective room, everything was ok, and a few steps later when I got into the teachers' room, when I was closing the door behind me, it happened. I managed to sit on a chair and then they realised I was not feeling well and gave me some water to drink, then I felt better and thought I could take the test, I sat down and a few seconds later I felt sick again and rested with my head on the table, my colleagues panicked and called the doctors, then I was able to walk to their room after a few more sips of water. I was given something to smell, sat down, they took my blood pressure and it was lower. I was allowed to drink some Coke.
This happened psychologically, due to fear, they told me...
My question is, how can I get rid of this fear?
