Just set small, short term goals. Maybe something like 10 pounds at a time, or getting into a pair of pants the next size down. I know that sometimes the scale isn't moving, but I'm still able to get into a pair of pants the next size down and that encourages me and keeps me going.
Sometimes if you look at the big picture, and how far you have to go, then it can seem overwhelming, but if you just look at small increments and take it one step at a time, then it's much easier to stay on track.
You can do this!!
