The one that I had in grade 7 was the result of being picked on constantly because of my religion, the out-of-style clothes my mother made me wear, and leaving it all in Jehovah's hands. I was bashed in the head, kicked just about everywhere on my body, and I did nothing about it - except leave it in Jehovah's hands.
The result was me shaking uncontrollably when I was at school, or even when the thought of going to school came to mind. I would shake while getting dressed in the morning, while I was walking to school, etc. It was horrible, and something I never want to experience again.
