I hear you!!! I don't know wtf is wrong with me lately either! Ever since I got my wisdom teeth out in Oct and sat on my butt for a week eating like crap, I have been just plain lazy. Luckily I've only gained 3 lbs, but still, I feel it's unacceptable as I was losing 1 lb per week before that. Don't get discouraged!! You still have enough time before your wedding to lose weight if you really commit to it.
I know this isn't an option for a lot of ladies in this economy, but if you can, get a PT. I've had one for almost a year and it makes losing weight so much more bearable. In the very least, see a nutritionist or someone that can help you come up with an eating plan that you can stick to and that works for you. We can do it!! I plan on losing another 20 lbs this year, so if you ever need someone to talk to or lean on, give me a shout or pm me!!
