You should raise the humidity. It should be on the high end of "moderate" or the low end of "tropical" analog thermo/hygrometers are not very helpful or accurate

you should be feeding every other day. Never feed back to back days unless the frog is a juvenile. There may be a digestive issue.

is there any sign of impaction? Lumps on the side?

you need to organize your response and be VERY specific and at least try to answer all the questions. It could be the smallest thing that is causing this.

Unfortunately a vet may be the only option. I would consider one...

at this age the frog will not be dying of hunger this quick unless infection has set in. Please try to remain calm and carefully read through both my advice and others to resolve the problem.
