*waves* we'v all been there hun. I was there just a few weeks back. . but you do get back on it with some strong motivation.. mine was gaining 2lbs one week when it got quite bad and i was gutted. Its amazing what that signifcant gain can get you to do, i was swimming and walking the lot, and lost 3lb the following week, and once i found myself back on track its been fine ever since. . i did gain 3.5lbs, which is the most iv EVER gained, and i would usually be gutted, but i know that i loved my fantastic weekend so i was expecting it. BUT 3.5lbs is alot to me, and could have easily knocked my confidence big time. and like you said, you dont wanna throw it all away. i suggest going shopping, getting out the house or try a sw baking day.. make sure you have lots of low-syn things around to munch on today.
i know wnhat its like when you feel this way, and its not nice.. and you feel like it could all easily go tits up completly, but if you know this, its time to do somthing about it. *hugs* you can do this, just dig deep and remember why your doin sw in the first place. xxxx
