I am not expert in any way, however, I have a 7 year old male that has gone through a very similar thing in hiding under his log and burying his head. At time he would get frantic trying to hide. He lost his appetite for over a week. So I took him to the vet because he was so lethargic and wanted nothing to do with me. She said he needed more UVA and UVB exposure and a calcium deficiency. I felt like a horrible mom. But she just told me to change his bulbs and use more calcium. ?.
So I searched this site and did what the vet said and tried something and it made a world of difference. Zeke is more active than he was in years.
I changed his "basking" lights to a Solar Glo and the ZooMed Reptisun 10.0 UVB Flourescent bulb on his cage. I wasn't too happy in the fact I had just purchased new bulbs a few weeks prior to these newer ones but I kept these in case the new bulbs burned out so I would have a back up until I could get the replacements.
One other thing I did was bought liquid calcium and put some drops in this water and put some on my finger and just rubbed his lips/mouth. Sounds odd, but now he drinks water w/ the calcium drops from a turkey baster.
I hope your girl will get better. I know the feeling and just offered what I did when in your place. It may help. My guy used to "bromate" in the middle of spring and summer for 2 weeks and then POOF he was awake again.
