not sure what to do about exams

I had my first psychology a level test today ( i’m in y13 so these acc count towards our final grade ) and before that i was a straight a/a* student. however, i had a slight panic attack in the exam and i started crying and i physically couldn’t write and i had around 10 minutes left so i had a lot of time. i left a few questions blank , so i know definitely that i haven’t done well. is it worth it talking to my teacher about it? i dont want it to seem like i’m asking for attention or something ig
