First and foremost, you must consider what the others are asking - is it possible she has parasites, or is impacted and not eating due to that? If you aren't sure, then a vet is recommended, and these problems need to be addressed first. If you can confidently answer no, then you need to force feed. I have a frog that has not eaten since October. I gave him regular soaks, and still no luck. the end of Jan, I began force feeding once a week. At first, he just let it happen, but after a couple weeks, he would struggle (indicating to me he was regaining strength). I force fed and soaked regularly for about 6 weeks. Guess who's eating on his own and gaining weight? What I think happened with mine is that he aestivated over the winter, and failed to "wake up."

There are some videos on youtube on force feeding. What I did was place the frog in a corner, or blocked him from backing up with once hand. I mixed pacman food with water until it was roughly toothpaste consistency. (I recommend zoomed to get the gooey-ness) and loaded it into a syringe, without a needle. I rubbed his lips until he opened up - you have to be a little assertive to get them to open up, but remember that you are trying not to damage their little mouth. And squirt it in. If she's able to spit it out, then make the food mix thinner. Some is bound to be spit out, but as long as you got some in there, I called it a success.

I force fed and soaked him weekly in slightly elevated temp range 82-85. I think the combo was what helped, soaks did not work alone.
