My Body... weak like a piece of paper...

At this time, I supposed not to sit here and I supposed playing around or joking around with my students. But, the fact is I am still here, in my study room, infront of my HB's comp. No doubt that, I sick again. Last night I felt giddy until nearly vomit and this morning I gastric =( Sometime I really get annoyed by my body condition, not that I reduce my meal. I took proper food according to the right time. But why I am still so weak? I am working under government and I still not over my interview yet, how my boss comment towards me? I swear I am not lazy ok! They always told me to take care of myself, have a good body condition only plan to preg. but problem is... I am still weak... how to plan?
