First of all Congratulations! Yes, you need to congratulate yourself for losing 59 pounds in less than 5 months. That's huge.
Secondly, I'm not sure how much more you have to lose, but perhaps your slowing down in the pounds per week lost process. That can feel discouraging. For me (lifetimer now for 4 years - but I gained back 13 lbs - and so have gone back to WW basics

The fat brat inside me, is very very sneaky

especially late at night and on weekends.
Some things that are helping me... I excercise and use those extra activity points. There are days / nights that I'm just plain starving. I find protein helps , like a couple of hard boiled eggs. Also fruit, yes fruit, like an apple, a bowl of cherries, 20 cherries equal only 2 points, sometimes does the trick. And yes, I eat a lot of grilled and roasted veggies. If I'm being particularly good, I cook them early so I have them to munch on later. A half a pat of butter some salt or soy sauce salt peper and minced garlic sauteed, and then baked / broiled and voila! heaven. Also celery and salsa is 0 points. I like the salt. Health Choice Organic popcorn or Orville Reddenbacher's 94% fat free - I believe are only 2 points for a whole bag. And those 2point bar help during the day.
I have gotten the 12 week journal and I am writing EVERYTHING down. Even when I have 50 point days. Thank G-d they'r enot very often. But it clues me in to how I'm feeling. And those feelings do effect us. I've started a 12 week challege thread - might be worth joining in -
Also I have a buddy I call when I'm shaky or have gone off program. It helps to commiserate. In addition, I find I have to set new goals - pretty much every month to keep my focus - and I need to give my self rewards.
Keep up the good fight... you are worth it.
