Your narrative goes something like this:
“Oh my gosh, if I fail this test I’m not going to pass this class. If I don’t pass this class I can’t graduate on time. If I don’t graduate on time I might not graduate at all. If I don’t graduate I’ll never get a good job and I won’t make any money. If I don’t make any money I’ll be poor and become homeless. If I’m homeless I’ll starve to death and die.”
Please, remind of the last time you read the news headline, “University Student Fails Test, Dies.”
No, you’re just catastrophizing. Be reassured that your narrative is so far detached from reality as to be comical.
Breathe. Be calm. You’ve come to learn, not to live in fear.
