God Bless You. Said a prayer for you just now. You need to start and then put one foot in front of the other. Take it a day at a time. Never give up. I suggest low carb, but others here might suggest another way. PLEASE take the time to watch this video.

Set mini goals and reward yourself every 10 lbs or so...but not with food...with a pretty colored nail polish, or a new hat or ribbon for your hair, etc. Never give up. Please watch the video. I don't think you'll be sorry. I wish I could tell you it will be easy, but it isn't. You have to give it all you've got and make it your priority.
