Eating :/

So today and yesterday I have only drunk some tea and some milk. I can not eat for some reason! I get horrible pains and it hurts extremely bad. I told my momma about them and she says they are gas pains?! What in the world ! I know gas pains hurts but geesh didn't know they would hurt like that. But since I am on nothing but a "liquid diet" everything seems to be a ok. I ate a bite of my brothers pizza earlier and the pains about killed me. It hurt real bad. But on the good note I've lost like 8 lbs bc of not eating. Not a good way to loose weight. But what can ya do when ya can't eat.
