No diary = no information but if, as you said, she perked up a bit after you watered her, it tells me you're not giving her enough water! When you water, you should be watering the entire pot and getting at least 10-20% runoff. For her, from the looks of the soil, I would water until that tray under her has some water in it and then let the pot sit in the water for a while - I think you'll find the soil soaks that water back up ... water her until the runoff is no longer being soaked back up and then pitch the water that remains because you don't want her sitting with wet feet..
Start a diary on her! Diaries help us help you when problems arise!
Good luck....
