Fresh start though eh!
Time to draw a line under the Christmas and New Years indulgances, find out the worst and deal with it.
I felt the same last Wednesday, and it was HORRIBLE. All the other that went and stayed had either lost or maintained, and I had put on 8lb! I knew I'd put a bit on, but wasn't ready for that info.
BUT, apart from the momentary shock, and the horrible feeling waiting for my turn in image therapy that I was the only person there who'd messed up (probably the others will come back this week eh!!) it was bearable.
If you go the worst that can happen is you face up to the truth and deal with it.
If you don't go back... well, you get to stick your head in the sand a wee bit longer.
PLUS - you might be like all the others at my class and find you've maintained or lost.
