Everyone should try that, and I'll bet that's the reaction most will get from the teachers.
I just remembered - I, too, was having trouble in ninth grade, and I told my mother that I was too nervous all the time and couldn't concentrate. So, my mother took me to our doctor who was the old-school type. The doctor gave me pills to take at school, and soon I was taking them a few at a time. I would feel differently - much more calm and subdued - after taking those pills. I told my mother about it, and that's when she revealed to me that they were just sugar pills. =) She was always a wise woman, my mother, at least about some things.
