Hi,
I hear what your saying since I've been thru it myself, and all I did was set myself up for failure when I set a goal of trying to lose weight for such a big event. Needless to say, I didn't lose the weight and that was over 10 years ago. Just the stress of planning a wedding is going to put you over the top.
You're going to look at my ticker and ask, What the heck? Why should I believe anything she tells me? Look at how much she weighs!! All I can say is, I fell off of the wagon. I WAS down 75lbs, so I know what works for me. I'm now back on track but have a long way to go to get back to my 75 lbs and more. But I won't give up, and you shouldn't either.
Your fiancee loves you the way you are right now, or else he wouldn't be marrying you. You have to find a way to accept that, accept yourself the way you are right now, and then make a plan of attack.
Take baby steps in your plan of attack.
1. Start with drinking more water, or some water if you don't drink it at all. If you're drinking pop, stop, even if it's diet pop.
2. Get up and move more!! That alone will make you feel so much better. There are so many threads here on 3fc that will help you and challenge you.
Find something that you will enjoy doing, instead of hating it. I joined the May steppers. I got myself a pedometer, and just walk walk walk, even if it's just walking in place, it's moving!
3.Join us on the 300+ thread where you will get sooooooo much encouragement, motivation, and support you won't believe it.
4. And most importantly, start a food journal. What I did was just eat what I normally ate for one day, or two,just too see how much I consumed so I would have something to go by. Believe me, they add up super fast and you'll be amazed at what you can put away. Then pick a plan, Atkins, calorie counting, Weight Watchers, whatever, just pick something that you think you can stick with....
and stick with it!
Take each step and do one or two until you feel comfortable with it, then add another one.
I really hope this helps. You'll have good days and bad days, but please don't stress about it. You have such a short time to your wedding and it should really be a happy time for you. The weight WILL come off!
Best of luck, and sorry if this sounded sorta harsh. I just want you to not give up on yourself. You only have yourself to rely on. There will be people who will sabotage you, but don't let them do it because you ARE STRONG!!
