This is true. I have really bad anxiety and if I have to talk in front of a class I will take a panic attack. Loads of the teachers at my school say that it's 'just a lack of confidence' and that 'by doing it more often I will get less nervous'. No I won't it's a mental disorder. I can't even talk to someone outside my friend group confidently enough because of my anxiety so by forcing people who have anxiety into these situations it makes them worse.
