I am not confident about my learning abilities even though I have been doing okey at school.Next two months,I will have my final examination.I have been worried so much about it.I am afraid I will fail.Besides,I often skip meals.I don't want to eat any food.I have been losing weight.I feel exhausted and cannot study well.At school I cannot think about my lessons, and so my grades arr decreasing.I would like to study well and pass the examination. I'd also like to have my meals regularly. What should I do?
