Oh no...I am so fat

Ever since i started work, i've been eating, working, sleeping and not to forget 'drinking' as well. I am officially fat now. For those who do not see me for the past couple of months sure will realize that i am fat compare when i was at uni studying. 4 months only and i have gain so much of weight. What the hell is happening to me. Need to control control control. I can't imagine what will happen to me few months later. Therefore from today onward, i need to start doing sit up at least 50 times a day. Eat less rice and eat small portion of meal. This is the least i can do to control my weight. I don't wan to be fatty chui. I wan to be skinny and pretty chui. *must keep my promise, HELP!!!*... i can do it!!!!
