My Crestie is Acting Weird

[RachStarkey]

My crested gecko is acting really weird. She is about 2.5 years old, we've had her since she was a baby. Within the past few days she has been lethargic, not moving very much or very well, seems to be trying to get as low as possible when i hold her (with her belly on my hand), and she has lots of wrinkly skin on her sides. She also no longer has any interest in eating her crickets, which are her main source of nutrition. We've started hand feeding her ripashi to make sure she gets some sort of food in her. Her last shed was hard for her too, i had to put her in a bath and help pull off most of the skin for her. I'm really worried about her and need some advice. In all the time I've had her shes never had a problem

A little info about her:
She has a water dish in her tank that always has water in it and gets sprayed using a water bottle continuously through the day.
Mainly eats gut loaded crickets dusted with calcium powder. She's usually very active and likes catching them herself in the cage.
20 gallon tank on it's side with a screen door filled with live plants and coconut fiber ground.
Apparently our thermometer is broken so I don't know what the actual temp in her tank is but it's normal, as is humidity.
Her appearance hasn't changed except for the wrinkly skin on her sides, she gets fired up at night.

Do you feed Repashy all the time or crickets? They don't need insects as often as they need the MRP.

Sounds like she may be dehydrated, having a calcium crash or too little D3. I would take her to a vet and check the temperatures to make sure they are not too high, they sell a digital thermometer/hygrometer with a probe for around $12 at Walmart.
