Throwing up water ?

Hillary
I wasn't sick at all this morning. 
I ate. Drank a bunch of water because I'm dying of thirst all the time. And I threw all of it back up. 😭😭😭😭 I can't drink soda or coffee. I puke that up. So water is all I have. And I'm aooooooo thirsty 😣 i don't understand why I would throw up what I need
