Oh I am with you today..!! I feel exactly the same. infact, I dont know, i feel better now and I could happpily kick myself.. but i felt that way earlier. I am taking today on the chin, putting it down to a bad experience (as well as being physically ill without a question... i would also question my mental health LOL) and thinking afresh as of about half an hour ago! As they say, never let a bad fail become a bad day and bad month.. i have always followed that when actively dieting and it stops me chucking the towel in!!
