I feel stuck in an endless loop. I've wanted to work in the railways for as long as I can remember and now that I'm so close to the dream, I'm starting to lose my cool. Due to COVID my exam keeps getting postponed which is making me anxious. My parents have a lot of expectations for me, I have to start supporting my family financially in a couple of years so a lot is riding on me clearing this exam. But the truth is that less than 1% people clear it in their first attempt. So things aren't looking up for me. The thought that I might fail keeps me up at night. These days even while I'm appearing for mocks, I start feeling dizzy. How do I fix this? I feel like I might get an anxiety attack on exam day.
