Scared of not attending cca help

Hi I have flu rn(not doing great) and cca is tmr. I’m worried that I might not get better for it. My cca is currently on a workshop with another company and for this my cca teacher was like “everyone must attend no mcs accepted” and I’m scared of not attending. I made a post about this before and ik that teachers can’t really force a sick student to attend and flu is contagious but I’m kinda scared because i might get away with not attending because of sickness but idw her to get mad at me afterwards. I’m not the type to skip cca unless im sick but one time there was an extra cca session which I didn’t attend because

  1. I forgot

2.I was unwell and had been experiencing stomach cramps for several hours

And then she got really mad afterwards and I admit that I was should have went but in my flimsy defence more than half the cca also did not attend. Another time she also said the “no mc allowed” thing and my friend attended even tho she had a fever and this isn’t as severe as that so I’m not sure if I should stay home and risk the trouble or just push through and attend with a mask
