HI BL... don't give in.... your mind is just tricking you.... If you give in you will feel ten times worse than you're feeling now....
I cooked the Friday night treat tonight... Pizza etc for the rest of the family... and had to leave the house whilst they ate as I suddenly got all panicky about how I was really gonna do this long term!
(funnily the only other time I felt like this was last friday)
Just remember it's only for a short time in your life, you can and will do it!!!!!
