I agree, she's very dehydrated and malnourished, and she needs to be given water dripped on her snout for her to lick off several times throughout every day, and allow her to have as much water as she wants, as long as she keeps licking it off then keep dripping it, and I'd be doing this 2-3 times a day. Her kidneys are likely very stressed, she may be dealing with a high Uric Acid level and Gout, which would explain the swelling, pain, lethargy, etc. So giving her water several times a day to keep her kidneys flushed out is going to be crucial, because if it is Gout then the fluids are going to be absolutely imperative to try to keep the UA levels from putting her into kidney failure.
If she's not eating any fresh greens/veggies, and only a superworm here and there and that's it, then this is not only another reason that she's severely dehydrated (they get most all of their
hydration from their fresh greens/veggies and live insects), but it's also part of the reason she's so tired and lethargic, she needs you to get nutrition into her.
Please don't wait to order anything or wait until Monday to see if she's still alive, as she may not live that long if you don't get lots of water and some nutrition into her. Knobby's suggestions of going to your local Petco or PetSmart and buying some Repashy Grubpie or Burger is the best thing you can do right now for her, all Petco/Petsmart stores carry the Repashy supplements, they come in black bottles and are powders that you mix with water. I'd go out and buy one or the other now, and also mix a pinch of calcium powder and a pinch of multivitamin in with the Repashy, and also you'll need an oral syringe to give it to her. She should be willing to lick it off her snout/lips, and you need to offer her the Repashy several times a day too.
Buying one of the Repashy food supplements is going to be much better for her than using just Baby Food mixed with some calcium and a multivitamin, as the Repashy food replacements offer protein, fat, carbs, etc. where the Baby Food does not, it's basically just water. The Grubpie and the Burger both are great and they usually really like them. I'd start feeding her and giving her water several times a day starting now, and then on Monday she needs to find an experienced Reptile vet to do a normal blood draw, so that you can get a full picture of what's going on. A routine blood panel will show whether she has Gout by checking her Uric Acid Level, it will show whether she has an infection or whether she's anemic, and it will also show both her kidney and liver function so the vet will know how to proceed with treating her.
Also, the Reptile Vet should give you a food-replacement, either Oxbow Critical Care or Emerald, both are great for them when they stop eating....
