Welcome, Holly. There are lots of caring people on this site who are here to encourage you. I agree with another poster, be sure and sign in when you are feeling blue.
ALL NEWCOMERS should browse the forum and read Pepe's recommended post on detox symptoms. Knowing that what you are feeling is normal will get you through many a cleansing crisis. Remember to follow Somer's great advice and never end a fast on a low - you will only stop the crucial detox and prolong the yucky feeling.
