I'm sensing your fear is a part of your detox. Emotional clearing can be just as intense as the physical symptoms. Feel the fear and keep pushing forward. Keep taking it one day at a time and try to refocus your thoughts on one or two solid achievable goals when those negative thought patterns emerge. Do you know how many people can Water Fast for even a day or would even consider it as a healing process? Not too many. You are already doing it! Day 4 is pretty amazing. Focus on the present, not the future or the past. You are beautiful right now, as you are. You're simply getting stronger and more resilient. Write down positive goals for yourself and refer to them often. Who's your harshest critic? Take a look at that deeply.
