I am sorry to hear about your frog acting strange. From my own personal experience I would suggest getting her stool checked by Dr Frye. I have heard so many good things about him on these forums.
This year I lost a chameleon. It was my first time owning one and the pet store gave me one with parasites. When I went back and told them about her eating problems two months later they never advised me to an exotic doctor or to have her checked out. I trusted their advice that it was just a behavioral thing. after a few months she started eating less and less but never lost weight (she was bloated). I brought her in and had them look at her and they said she was fine. I should have had her stool checked out because a few months later she fell and died from broke ribs because she was so weak from the parasites that she couldnt hold on to her branches. I only had her for 8 months.
It was a hard lesson to learn because I had to watch her slowly and painfully die. I still think about her every day and regret not knowing about the signs of parasites.
I hope that you at least get the stool checked out.
