Hit by Migraine

I have been hit by migraine the whole day.  Today was my first refresher course, and i had the lesson near my place, it was at a quiet car park where traffic was very little on a sunday in the neighbourhood.  i don't know why but i am so nervous and the feeling is like i am first time driving!  My license was obtained 4 years ago and its a Class 3 license where i got it driving a manual car.  Today i opted to drive an auto and somehow i am completely lost.. i am so nervous that after the lesson i was hit by migraine.. Dear brought us out to Orchard after my lesson and the headache was even worse (except that a period of time, i was busy trying clothes at the CK outlet that i forgot about my migraine ).. the headache hit me the worst around 9pm and i felt that i am collapsing the minute we got home.. i really don't know if i am cut out for driving anot.. i used to enjoy it 4 years back and i am very confident driving on the road... but today, even in the isolated car park i am so nervous that i am totally stressed out.. esp the thought when i think of Cepheus seated behind me in the future made me even more freaked out!  I guess Dear better go get a license soon.. if we were really adamant on getting a OPC next year.
