Hi, Please dont cry! Beating yourself up about it will only send you into a shame spiral which if your anything like me will lead to comfort eating and then we are right back where we started. As others have said draw line under it or through it or write down what you have over indulged in on a piece of paper and rip it up or kick the cr*p out of it (that always make me feel better though perhaps i am a bit mad).
I am not back on plan yet but have been trying to be good for the last three weeks. This week I have also had family upheavels then a domestic with the other half last night and the feelings of resentment spilled over into today (mayb I should write his name and a list of his faults on a bit paper and kick the cr*p out of that) so last night I overindulged in some very naughty sins. This morning I found myself thinking sod it am going to get a takeaway for dinner but instead I went for a drastic (sin free) haircut instead I feel much better now and I'm too skint to get a takeaway not that I want one now.
Good luck with getting back on the wagon. Take Care x
