Appealing Medical Country Restrictions

Hello,

I applied for a position in Nepal, and it is my dream to be able to serve there. I love Nepalese culture and have a deep affinity for the country. Three years ago I had a one off seizure and was placed on a medication for a couple of months. I was never diagnosed with a disorder and have been off the medication for three years now. However, I did disclose this on my medical form. Peace Corps has informed me that I cannot be considered for Nepal due to my medical condition, but that I can be considered for other places. I am absolutely devastated as I am unfortunately not interested in serving in the other countries that were offered. Does anyone know if it is possible to appeal the decision? I realize Peace Corps is very safety orientated, but this seems very extreme as I am not on medication nor do I have a disorder.
