Sick sick

I have been having fever for the last few days; internally the body feels hot and externally, I feel very cold when exposed to the air.
I had to sleep without the fan on and still chilling myself out....
It was really dreadful..
I was even so freaked out to apply for MC and was wondering whether I should or not:(
I know, sounds crazy but I am not a workaholic lar...I was just feeling bad at taking medical/sick leave...like it's some kind of injustice to boss and company.
I do fall sick frequently sometimes; since school days:(
Anyway, I came to work yesterday and finally, I couldn't bear it any longer when the heat on my forehead got to me and I was seriously having the fever spell again.
After some time of self-debate, I gained the courage to ping my boss and ask him for a half-day leave as I was seriously not feeling good at all, so pitiful.
By right, I have the right to be on sick leave as I do have the doctor's certificate on my absence from work and the doctor did indeed issue the leave until yesterday.
I just felt bad at asking for leave.....
Thank God, today I am feeling much better though some still say I look rather pale...
Well, what can I say after 3-4 days of lying down in bed and having heat all over body?:p
