Weight Increased?

Don't know what to do! Should I just quit my job (Before that need to find new one) or just try to keep up with it....
Ever since i work there, my weight has steadily increased instead of decreasing despite of all the tensions and pressures that i had went through!
To make it worst, my new Executive love to treat us whenever we achieved the target.... and my NEW MANAGER will treat us more than she does.
So what to do? I begin to sense that I'm sick for gradually increased my weight ( i already stop eating after 8 pm unless if I'm really20x hungry)
Ya ALLAH, if this really continues then at the age of 25, I probably won't be able to stand on my feet anymore....... sigh
