why i've fat tummy?

Another day has passed. Tons of foods were ate by me. 5 meals a day. Yay!
No doubt, i've realize that the more i work, the easier i get hungry and it ends up eating more food everyday. From the previous 4 months holiday and the half month working, i've gain 5kg! Its true! I don't know why. Perhaps too much shit inside my tummy? Owhh i've constipation ya? Cannot fully shit out all the wastage, then keep it inside my tummy and thats why i've belly now. Otherwise must be because i'm pregnant now thats why i've a round tummy. So fucked! I'm so so so depressed now. Everyday look at my round and big fat belly, feel like wanted to die. But, if i didn't eat so much, i'll feel very very tired and hungry. Haih. Life ah. Why thing like this also will bother me? Haih.
