Don't stress. .. it happens to all of us, particularly to those who might not have a huge amount to lose. In any case, just look at overall trends.
My thought, that's kept me going, is that I am building healthier habits and I didn't gain the 110 pounds excess overnight.. so far since January I've lost 72 of it
but have lost a few of those pounds more than once.
What I do find is that I am more apt to lose consistently if I am absolutely faithful about writing down EVERY morsel. And if I drink plenty of water, since that seems to keep me from retaining water.
You're the one in charge, so celebrate yourself... you will be healthier, fitter, more energetic... it's not an on-off switch, but a journey. So go for it, enjoy the ride!
