Fasting is emotionally straining especially in the beginning. Next time around you'll be better prepared. Practice makes perfect. There is little we can do to avoid outside stresses, so try to take it easy, don't push yourself too hard, listen to your body and be good to yourself!

I keep screwing my fast up too, so I'm right there with you! I tend to be too hard on myself when I feel I failed, but you can't fail if you don't quit, starting over doesn't count as quitting!! Focus on the positives -

Best of Luck!!
