Lately I have been doing really terrible in chen and tomorrow we are having a really big test that I have been studying all night for. It's now almost midnight and I can't remember anything I didn't sleep well last night and I probably won't get too much sleep tonight plus I'm extremely nervous about this test and it's making me sick. If I go to school tomorrow I know I won't do well so should I stay home and rest? I already took off 2 days this year due to illness and I feel guilty taking off another one....
