Do I have anxiety, panic or just scared?

I'm 17 years old, M. I have a question because I really don't know, but every time, like, let's say in school, A few minutes before I get called out by my year head, I start overthinking and my heart races; it feels like its going to pop out of my chest and I start shaking and my voice goes shaky as well, but I know I won't get in trouble, and it keeps going on until a few minutes after getting called out.
