stuck in neutral and thinking abt quitting.

SOOOOOOOO frustrated!!!!! I have spent almost a WEEK at 143.5. I can't move! I need a nudge, a boost, SOMETHING! why am i bothering to work out if im no longer seeing results????????? and like today, im doubling up bc i skipped yesterday. and it's actually warm out for the first time in weeks, so i thought i might even supplement with a walk. but why should i bother? im expending all this energy for nothing at this point. even losing the weight slower, i still dropped at least a HALF a pound every few days. I'm STUCK! maybe this program isn't working... ok, I'm giving it one more shot. im going to go do my 2 days worth of workouts, go for a walk, have a protein shake, and that's it. when I weigh in tomorrow, if i don't see something change, i quit.
