Any success stories of 50 pounds?

I started my "new" lifestyle on Oct. 25 2012, it has been one of the hardest things I have ever done so far. Some days it feels easier to just eat Mcdonalds or grab a pizza for dinner. But anyways, I have lost 52 pounds so far. I started out weighing 279 to 227 right now. I want to be around 170-150. Went from a tight 24 jeans to a tight 16, 2-3x shirt to a large, xl shirt. I eat about 1500 calories and go to the gym 5-6 days a week for about 2 hours. I eat pretty much what I want (have to live with feeling bad, if a eat bad) as long as its in my calorie count for the day. I feel soooo much better. I can walk up stairs easier, can jog longer without stopping, my feet and back don't hurt. Sorry no pictures, don't have any and don't know how to upload them.
