Hi there!

Like Cassie said, sometimes anxiety attacks can happen on the spot without any obvious cause or reason. Have you been diagnosed with an anxiety disorder or any condition associated with anxiety attacks? If so, it could be helpful to inform the school.

Whenever I get an anxiety attack in class, I scribble on a piece of paper or my book. Sometimes I write down some of the thoughts that come into my mind, or I just draw random objects or patterns. It can actually be pretty calming. Other than that, you can try to focus on something happy, or anything else in the class room.

Hope this helped! Feel free to PM/VM me if you ever need advice again.
