Beginning water fast, unsure for how long, encouragement needed

Hello All!!!!

I am so glad I found this site. I am doing a Water Fast for my last week/week and a half in france for the year and returning to the U.S. on the 20th. My goal is to go at least the 12th (well, technically the 11th at 7pm) through the 20th (9 days total). While my host mother in france knows of my fast and is supportive and understanding, my family in the U.S. would think I am INSANE!! I am nervous as Christmas approaches when thinking of what I will do around that time. If I want to continue when I return home, I could probably get by with eating small portions of vegetables, raw foods, etc. Otherwise, I will have to be careful with juices and introducing raw foods into my diet around the tempting holiday time. But I want to do it.

This past week I did two 30 hour water fasts, and at nearing that 30th hour is the hardest for me, physically. I hit a REALLY low-low, and get very anxious/unsettled. Does anyone have any suggestions such as what you do during this time? I was way too much those days to really do the Water Fasts but I did it anyways, and I know that could have contributed but I also expect to have difficult days in the long fast. Any suggestions appreciated! XX God bless to all and much peace all around!
