How to lose the last 10 lbs?

Don't deny yourself delicious foods that you enjoy. But if you're craving chocolate, don't grab a bag of chocolate chips; grab ten chocolate chips. Enjoy them! Don't feel guilty about them or about any food--enjoy it for the wonderful experience it is. Focus on moderation. Try to get the most enjoyment out of healthy things--a fresh peach, a great salad, delicious grilled chicken. Eat slowly and enjoy yourself.
One of my best tips is largely applicable to restaurants so this helps mostly if you eat lunch (or dinner) out on a semi-regular basis. I ask for half for here and half to go. That way I get to eat and enjoy everything on my plate without feeling deprived, I'm full, and I have a second meal for dinner or for lunch the next day. This could also be applied to meals you prepare at home; simply serve about half of what you normally put on your plate. Try not to snack while you're preparing food.
Don't skip breakfast and be sure to get plenty of protein. (I add protein powder to oatmeal in the morning--you don't have to have a big breakfast but sure to have one!--and if you like cottage cheese, it's an excellent low-cal source of protein and you can add fruit, nuts, honey.)
The most important thing--and since you didn't mention it, I'm not sure if you're doing it--is exercise. Find something--ANYTHING!--you enjoy and make it part of your everyday routine. Classes work for me because I love the team energy and the camaraderie but for you it might be a team sport, hiking, or even just regular evening walks. Whatever it is, YOU MUST STICK WITH IT. Meaning, when life gets in the way--which it will--do not move exercise down on your list. It's a good idea for me to have a goal of five days a week because sometimes, no matter what you do, something will screw up at least one of your days. Do whatever it takes to make your exercise happen; on your weight-loss journey this should be Priority One. Don't forget strength training. (Cardio is important and that's how you burn calories, but the more muscle you have, the more calories you burn during cardio. It also weighs more than fat so it looks better on your body AND it increases your metabolism.) It is my opinion that long-term health (and the ability to actually keep off the unhealthy weight you've released) is dependent on exercise. Remember that you aren't taking off weight just for the cosmetic effects but for lifelong health benefits.
A huge congratulations in conquering your eating disorder. That is such a massive accomplishment in itself! And whatever triggers you might have in that area--you know what they are--be sure to NOT subject yourself to them even if you think you've got in under control and even if it involves some helpful advice someone (including me!) gave you. The MOST important thing is keeping you mentally healthy and feeling happy and satisfied with you as you are. Best of luck on your journey!

How to lose the last 10 pounds
For accountability, I belong to TOPS (Take Off Pounds Sensibly) which is a very inexpensive volunteer club with chapters in almost every town, and I weigh in weekly to reach a weight set by my doctor. Losing the first 50 pounds was the easiest, but losing my last 2-3 pounds was the hardest. I rode my exercise bike daily for an hour or more, but on the weeks that I succumbed to 1-2 sessions of binging, I added jogging the track for 5-10 miles. I'm in my 50's and hate jogging, because I had a bad fall last year. So, as a good deterrent to binging, I have photos of myself in my jogging clothes on my fridge and food cabinet. This helps remind me to do what I can to not binge, or keep the binge short, so that I don't have to jog. Also, I tracked my food and calories on myfitnesspal every day. I planned my meals the day ahead, and planned in small treats, that were low in sugar, so I didn't feel deprived.
Now that I am maintaining my weight loss of 120 pounds, I have to stay within a KOPS (Keep Off Pounds Sensibly) leeway and it is darn tricky. Maintenance of the weight lost, is a whole 'nother animal from getting to the goal weight, but it allows me to learn how to cope with life without eating my feelings. When I have the urge for a specific food, I know that I am dealing with a feeling and not hunger. So, I try to comfort myself with non-food activities.
So my non-medical advice is:
1. Have your doctor approve your goal weight.
2. Join a group for support and accountability.
3. Exercise regularly and track your calories. For binge eaters, it's easier to increase the exercise (reasonably) than to decrease the calories.
4. Plan small treats, but comfort yourself with non-food activities when you're struggling with feelings.
