am I ...

why is it that I always get headache right before exams?

Plus, I have this syndrome of saying things insanely. Like for instance, I say that I'm having stomachache and hold my tummy when I actually am having a headache. Tell me that's odd, but that's me. And few words confusion like let's say "x bwk duit utk makan", sometimes I might just say "x bwk mkn utk duit". This happens so frequently that it makes me feel that I need to see a doctor.
