I was dabbling with the idea of not going to group, but I realised that I need to see that number on the scales to learn from it and make me realise that I need to draw a line under it and move on. Otherwise I'll be sitting there wondering "what if it wasn't as bad as I thought? What if not going has made me lose focus? I wonder what that number could have been" etc etc.
We're getting so close to target now, that anything is able to throw us off track, whether it's a couple of days off plan, water retention or just plain old hormones! We'll get there though - this is a long term thing, not a quick fix. It took 21 years to get to the size I was and I know that it's not going to come off overnight. It's been an on/off journey spanning 3 years now and I am frigging determined to get to target this time! If you look at the bigger picture, I bet your achievements are amazing - what harm is one bad week of that journey really going to do? Nothing in the long run. When you're at target, you won't care about "that" one week where you gained x number of lbs.
I also weigh tomorrow night, so how do you feel about a challenge to lose what we've put on + 1lb?

I don't envy your workload at the moment, I hope things start easing up for you soon. You'll probably find it easier to stick to plan once it's all done xoxo
