I had the dizziness and nausea once because I was holding my pee in....in a math in 10th grade and the teacher wouldn't let me go. I told her I felt sick and she didn't believe me...so I sorta fainted on the ground and I got to go to the bathroom in the nurses.
As for being sick. I have been sick multiple times and gone to school. I vocalized this....so when I am really sick...it is legit.
