I was right where you are just 6 months ago, Jodi, and today I'm just 1.1 lbs away from losing 50 lbs.
I've been overweight since high school. I lost 35 lbs about 7 years ago, but that diet was not a lifestyle I could maintain. I got off and gained all of the weight plus much more back. I got used to being heavy and didn't really care.
Next thing I knew my DH started having some serious health problems, I turned 40, I was starting to be physically uncomfortable with achey joints and such, I was tired and slept way too much. I knew I was going to have to do something about my weight or I would be having serious health problems as well. I sure didn't want my kids to have to face life with no parents. Still, I did nothing. I did lurk here on WISH and watch the other people having great success.
Like CALIFLADY said, finally "it clicked" whatever "it" is and I decided it was time to do something. I knew I would get another year older and I would either be worse off or better. I finally chose better.
I agree with Mowsie dreamer, you have taken the first step by posting here. You wouldn't do that if you didn't want to make a change.
And like Doe said, make changes in steps if that's what you need to do. You don't have to do it all at once. I started by finding an eating plan that I felt I could live with for the rest of my life. This is not a short term fix. You need to be able to maintain after you've lost the initial weight. Next I cut back on caffeine. I still have not eliminated it entirely, but I'm much better than I used to be. After I was comfortable in my eating, I slowly began to add in exercise. I'm still not where I want to be in regard to level of activity, but I'm working on it.
Anyway, that's my story. I hope you can find something to relate to and know that you can make positive changes in your life too. We'll all be here to support you when you decide you're ready.
