You didn't give her enough water... When you water your plant, you want to see at least a little bit of runoff every time. In this case, make sure there's a saucer or something under the pot to catch the water and give her enough so that some of it goes into the saucer ... and let it sit there for a couple of minutes. It will most likely be soaked back up into the soil... so then you give her some more, again until there's some in the saucer, and again wait to see if it's soaked back up... do this until no more water is being soaked back up into the soil and then throw away the water that remains in the saucer. She's terribly, terribly thirsty....
Good luck!
