Losing weight for my wedding on June 5

Hello, my name is Jennie. I am 29 and I joined to lose weight for my wedding on June 5 next year. I weigh 170 right now at 5'5" and I just want to feel beautiful. I looked my best at about 135 - 140 lb., but that was 10 years ago and my fiance, who I have been with for almost 7 years, has never seen me skinny. I dont even have any pictures from back then to show him... it would just be amazing if I could get all this extra weight off in time for our wedding. He has loved me at my heaviest so I want him to see me at my best and to feel like I used to!!
