I Feel Horrible

Just finished a test and was certain that I failed it. There was a lot of careless mistakes. The essay part was very rushed and I had to redo one question because I accidentally used a different source to answer it. Worse of all, I had been very anxious and panicky because this test will determine whether I will stay in the current grade or drop below but when I got the papers I realized I did not study on that topic well enough to write much about it. I've been working so hard for this test and yet again I am going to fail. I feel like I work hard for so much but just never do well. I think I'm about to cry.
