GTP- Weird skin wrinkling- HELP!!

[Will0W783]

I noticed my GTP's skin is very wrinkly and seems loose. She's been eating fine, one to two jumbo f/t mice a week, but her skin was looking very hazy last week so she did not eat then. It's been two weeks since she ate. I would think she is going to shed except that her eyes are not at all cloudy. I have a MistKing system that mists for 30 seconds every hour from 8am-10pm and once more at midnight, so I can't see how she would get dehydrated. She also has a large water bowl that I have seen her drink from. The temps up by her basking lamp at the top of her cage are around 90-92, and in the lower perch area and floor it's about 82-84 during the day. The room drops no lower than 78 at night. I have a room heater that kicks in as soon as the temp drops below 78. I am rather concerned- could it be she is going to shed even though her eyes are not cloudy? Her skin looks dry and like it is going to shed, but the wrinkles are what freaked me out. I am going away on vacation on Thursday, but I will have a neighbor come every day to check on the snakes and make sure everyone has water and is ok. I will be back the following Tuesday, so not too long. Any advice would be really appreciated...I'm worried about my sweet Mystique.
