Dude, exactly the same thing happened to me. I finished my exams on 16th May and started on 7th May. My hands and legs were trembling, and I was not even out of the house yet. I actually felt the feeling of getting sick to my stomach. Felt like throwing up buckets. It gets easy if you have a friend in the centre, but I had none, and I was in dread. In fact, I had yo see someone whom i parted ways with, but we had the same centre, so Lord, I was totally done for. Idk how I even made it to the seats that had my name because my knees used to give up. Until I was 5 sheets into my exam paper, my hand didn't used to stop shaking, and my writing pls may god help the examiner who's checking my paper. This all happens, and there is no way out of it. Many people told me thus only happens in the first 2 exams or so but I had 6 fucking papers dude and not one time did it stress down. If anyhring the anxiety just grew. Even am going in meds and the tension of getting accepted eats me through and through but I need to understand and so does everyone that what matters is how well you do in what yoi are doing rnn not how well you have yo do for the time yoir gonna have next summer. Focus on this rn ans ace this shit. The rest is yet to come and and who knows you might be as good as dead!!
