I don't know what to do.

I am 14 and I tried water fasting. I wanted to do it for 30 days, but it was July 4th, and on my 10th day, July 4th, I failed and ate. I feel really bad, and worst of all, my parents think that this the most dangerous thing to do. Furthermore, when I told them I needed more rest, they yelled at me a lot that I am stupid and that what I am doing won't help. They made me do a lot of heavy work, and eventually it got the point I had to quit. I want to do this fast, but I don't know what to do because they will force me to do exercise when I am trying to conserve energy for this water fast. I really need help. Tweet
