STUCK AGAIN!!!

Well i have gone and done it again i got down to 170 this past friday and Tuesday wheni weighted my scale was yelling at me that i was back to 183.I don;t think that thing likes me, it's brand new and its talks but i might just break it abfter this weekend. i work so hard to get those lbs. off and now i have to do tit all over again, damn it!! anybody got any suggestions.Sat is my cheat day but i think i am going to just forget the cheat day and just stay on the diet 7 days a week, what could it hurt? at least i wouldn't maybe have to back again and lose those same lbs. again. i hate that and it makes me feel like a failure.Let me know i am up for any suggestions or motivation. i have been fighting a bad back for about one week though so my moving around has been limited. that is part of the problem.any help would be appreciated. been using my old walker to get around.

Thanks

Susie
