I think it's weird that I want to catch the flu
What is your reason for wanting to get sick and catch the flu.
I just do not want to have to go to school.
It's normal to not want to go to school, but getting sick just to get out of it can lead to bigger problems and serious consequences. Talk to a counselor and find out if there are ways you can enjoy going to school and stay healthy.
Fake illnesses are fine.
Well this is just a bad habit to get into. Playing sick to miss things that are important will cause you to later on make excuses to avoid stress. Just do your best to overcome this stress and make the most out of these uncomfortable situations.
