三one possible version:
I quite sympathize（同情）with you and understand the great trouble you are suffering from. No matter what is troubling you, don’t blame yourself for not doing well. I suggest you communicate your trouble to your teachers and classmates, as they may help you out of the tough situation. You are not supposed to think about your exams all the time, which only makes you more depressed. Instead, you should think about the progress you have made in your study, which will surely increase your own confidence. In addition, I advise you to do more exercise in your spare time to relieve your stress, because sports will also help you sleep better at night. Only when you feel energetic can you concentrate on your study.
I hope you will get out of your trouble soon and live happily.
