Can you elaborate on what went wrong with the force feeding? Was it entirely in her mouth when it was kicked out? How many attempts were made? How big was the food, how large is the toad, and (importantly) was it dusted with a fresh multivitamin, not undusted or with calcium? Months without food is certainly worrying, but depending on how fat she was at the start, it's hard to say if she's in any immediate danger without knowing her weight, or seeing a photo of how skinny she's getting.

I feel like at this stage, you really have two options. You do everything you can to keep her calm, unstressed, and in as good of shape as possible until the vet returns, while doing research and hoping for the best. This means probably ceasing attempts at force feeding, which are stressful as hell, as you no doubt are aware.

The other option is to try to do, well, basically the above, but try getting some appropriately dusted food in her. Since you mentioned using a card, I assume you've looked up how to safely (or as safely as possible, anyway) force feed toads. If she's starting to get pretty thin, I'd probably go this route, but I honestly don't know if it's the correct one. If she's sick due to some sort of vitamin/mineral deficiency, the sooner she starts getting the fix in her, the better. Vitamin deficiencies can take a fair amount of time to correct.

Lija, honest question, but can parasites get so severe they entirely kill a feeding response? I have (fortunately) had zero experience with parasites of any sort.
