Well for a start the last thing you need to do is beat yourself up about it! Otherwise you will end up on very big slippery slope.
What is done is done - no changing it now. What you need to do is concentrate on being 100% from now on in.
It's so easy to have a blip! More important now is how you move on from that. Forgive yourself and carry on all the fantastic work you have done so far! You know you can do it, you have proved that!
One question to ask yourself is: are you worth it? Ans: of course you are worth it! The last thing you want is that slippery slope of guilt that means you give up!
PS big secret here! But you are this weeks biggest looser AND biggest % loss too. A winner twice in one week! Now that's got to be a record! Xxx
