Hi NDupler -
I'm sorry you feel so helpless at this time - in order to not feel helpless (which we have ALL felt before we changed our lives!) you must take your own destiny in your OWN hands, and make good choices every single day. Eat less. Move more. START SMALL.
Eat less sugar this week, maybe, and keep a promise to yourself to walk for fifteen minutes every other day.
Next week, start counting your calories (this works for many people - you may prefer to try some diets and find one that works for you) - try looking at The Daily Plate or FitDay - these are wonderful resources for tracking what you eat. Don't be silly and start out at 1200 calories a day - you'll end up hungry, and more importantly, with nowhere to drop your calories to as you lose weight.
Drink more water on week three.
READ POSTS HERE. There are lots and lots of little, easy changes you can slip into your life that will help you to feel better, slimmer and more in control of what you eat and how you live your life.
There is no 'secret to success' - it is a combination of dedication, determination, and consistency.
Read people's stories in the Goal and Mini-Goal forums - these are SO inspirational - and every one of those people will tell you the same thing: if they can do it, YOU CAN DO IT.
And you CAN.
Post here with questions and read lots - you'll soon find what works for you and remember: time will pass whether you lose weight or not - so why not start right NOW, and not lose another day??
Good luck - keep posting and telling us how you are getting on!!
