How do I survive through this week?

  This week is our final week, and I have 8 finals. I can hardly breath because the amount of test is so much.
  Tomorrow, I am going to have three tests, and I plan not to sleep tonight. Every time when final exams approach, I feel so anxious and nervous, because I am so afraid to get bad grade.
  The ways for me to feel better is to think about the upcoming summer vacation. In July, I am going to France, and I really look forward to the trip. Another way for me to lighten my pressure is to eat lots of desert. The truth that desert can make people feel happier has been proved by scientist. Finally, the last way, which takes more time to do, is to watch funny animals videos. I often type "funny cats", "funny dogs", "funny parrots" on YouTube, so that I get to watch some ridiculous and curing videos. This is actually the most useful one.
  These are my ways to make myself feel better, what are your ways?
