(((((((HUGS)))))))
First of all, you CAN and WILL shed this weight. You've done it in the past, and you are capable of doing it now. How are you feeling? I bet you are feeling pretty darn proud of yourself for being HEALTHY and exercising and eating right and STAYING IN CONTROL these last few weeks!

Don't forget that! Numbers on the scale really don't mean EVERYTHING as they can and do fluctuate.
That said, I can totally 100% relate to how much it sucks arse to not see that # go down! It totally blows! That's what we have to 'reward' ourselves with since we can't reward with food... and then to be doing SO good and be so excited to see the progress, only to be disappointed? ugh! One of the worst feelings!
But remember how you felt just moments before stepping on that stupid scale... GREAT I imagine! Because you are doing WONDERFUL! There are all sorts of reasons as to why that # may not have gone down right now... I've been known to do exactly what you did, eat great and exercise a ton and GAIN FIVE POUNDS simply b/c it was at a point in my cycle where things went wonky. It WILL come off.
I mean, what's the alternative? Not work out? Not eat right? Because then you'll feel guilty, and likely gain... and six months from now thinking "if only I stuck at it I could be this much closer to goal... or AT GOAL!" I mean... you don't want to regret giving in now. Think about how you would feel at Christmas time this year if you stick with it... you could be so much happier with your body! It is totally worth it to stick with it.
I'm here for you, girl! I know the disappointment of doing such hard work and not seeing the progress on the scale. The important thing is that you're feeling proud of yourself rather than guilty or ashamed, and you are gonna stick with this. The weight WILL come off, it might just surprise you every now and again by how it chooses to fluctuate. Hang in there, I know it's frustrating. *hugs*
I am VERY proud of you though for all of your efforts... KEEP IT UP!
