Weigh In Wednesday Riddle

Warning: whiny post ahead.

Riddle me this:

I stayed within my calories 6/7 days this past week (and the one day I went over was a 14 mile run day so technically I was way under because I'm sure I didn't eat enough the rest of the day).

I exercised 5/7 days.

I'm drinking my water (excuse me while I run to the bathroom to pee, again).

I'm down a whopping .4 pounds (that's POINT 4, as in less than half a pound).  I should really re-weigh myself when I go home for lunch though because I've had major GI issues all morning and I must be down another 2 pounds. TMI - you're welcome.

My measurements are the same.

Why am I making zero progress?

Awful. I really don't remember when my waist size was as big as it is now. Seriously, even at my heaviest I always had a smaller waist. And that number I said I'd never weigh again? I'm almost into the decade above that.

I really think I'm stuck here and "here" is a really crappy place to be. I'm pissed and I don't understand why this is now impossible for me.  This is why it is so hard to stay motivated. I do everything right and I still fail.
