All of the below is written with the assumption that this is not related to medical issues.

You didn't gain the 90 pounds in four and a half months so it is very unrealistic to expect to lose it in such a short time. You would have to burn 2300 more calories per day than you consume to do that. If you start to realize you are not meeting those goals, you will become discouraged and if you're an anxiety eater, it will defeat the whole effort.

The realistic solution is not to base it on a specific date, change your lifestyle. Eat about 2000 calories and walk four miles every day, FOREVER. Don't weigh, changing ratios between fat and muscle can be very misleading. You're looking for a size reduction anyway. There's not going to be a weigh-in at the dance. :-)

It will help if you adopt a vegetarian diet. Fats have twice the calories per gram than carbs or protein. Eat all of the vegetables and salads you want. They are filling and the fiber is very low cal. Drink all of the water you can hold. Don't consume drinks with sugar.

You will lose a lot of your size at the start and the rate of loss will gradually decline. Expect that. You will lose a sizable portion of the 90 pounds but probably not all. The important thing is that you will put your weight and size loss on a realistic and sustainable trajectory that will decline to a normal size and stay there.

Be aware that this is more of a psychological than a physical issue. When you face the things that would normally trigger a trip to the refrigerator (anxiety, boredom etc.), you have to replace that with something else. A good way to deal with that is when you find your hand on the refrigerator door or a bag of snacks in your hand, make that your trigger to go out and walk a few miles.

Once you've changed your habits, get busy, get active and don't look back.

I know people who've had success with the www.sparkpeople.com. It's a free weight loss networking site where you can track your successes, get email motivations, and interact with others who can help you stay motivated. Good luck.

Also, keep your diet low sodium, high sugar, and nix the sugar and simple, refined carbs (white bread, white rice, white sugar) in favor of whole grain foods.

I think an important part of losing weight is staying motivated. A lot of the time people get on diets they quit there diets because they are not motivated. If the dance is you motivation keep your eyes on the prize and don't take your eye off of it. I don't know a lot about losing weight but I know that you have to have something that drives you. I hope it works out for you.

You know "The Hump"? they say that once you get over the three-day hump of trying to get into a routine it starts to stick. I think thats true more or less so dont give up! Stay to it and if temptation comes along to eat unhealthy foods or to stop exercising remember how good your gonna look or how good your gonna feel for pushing yourself to accomplish your goal.

It sometimes helps to plan out your meals so if you see something you want thats against your diet you'll know you already have something waiting that you can go and grab.

Also, losing too much weight at once is unhealthy and can actually do more harm for your body than good. Find a reasonable goal. This will not only be healthy but wont stress you out as much; worrying about losing a ton at once or strictly changing your diet so suddenly.
