We all go through slumps.
First, you're dealing with a slowdown in mood. Sometimes we have to fake it til we make it. And, you know, exercise actually helps improve our mood. Maybe we won't be bouncing off the walls, but perhaps we can move up into "content for the time being". Remember your tagline under your name "Not stopping at ANY cost". Do you remember why you wrote that? How it felt to write that?
Second, you're dealing with your first gain on WW. It happens eventually to all of us. I've had small (and some large) gains many times. It's disappointing, and frustrating, and yes, a little scary. "Crap! Does this mean I'm going to gain it all back?" Irrational fears and all. One more week. Fine, the scale says up .6. Doesn't mean that next week or two weeks from now will show the same. Back to plan, even if we aren't happy-go-lucky about it.
If you feel you can't get in as much exercise, even a 15 minute walk will help. Something is always better than nothing.
