Hey girlie. First off, very well done on you weight loss so far thats really fab..
I just have a few things that i'd like to suggest to you, the first being the way you visulise the sw eating plan.. if you think of it as a diet, it will ot work.. you will crave food and you wont keep the weight off.. you must see it as a way of life and enjoy it, relax and be proud of what you have already done. sounds like you really need to make it exciting, new recipes.. new things to try.. and treat yourself when needed and syns allow.
i know it may seem that it is not coming off quick enough, but it wouldnt be coming off at all if you wernt doing it at all! Sw provides slow and steady weight loss of which your body can ajust to easily and maintain and keep off. So i think aslong as your getting off atleast a pound a week, then your doing absoloutly fine. Are you eating lots of free food, super free foods etc? I wouldnt stress about the weight gain, it could be for all sorts of reasons like peperclip has mentioned above!
stay focused and motivated and keep yourself busy, well prepared and stocked up.. relax and just take each day as it comes.
sounds like your having a really crappy day anyways, so maybe you should write today off and start again tomorrow?/ Hope you feel better soon ... lots of love x
