Hi Keisha!
Like everyone else has said, welcome, and take your time.
Try not to think way in the future with this...stay one day at a time. Each moment presents a new opportunity to feel good about your choices. We're all trudging along, and hopefully can support one another to get where we're going.
One suggestion -- go look at the before & after pictures, and read the success stories. HIGHLY MOTIVATING! Really, when I was feeling discouraged and down on myself for not staying on my program, I looked at those and read about the people, JUST LIKE ME, who stuck with it and overcame the odds! But they did it one day at a time.
Glad you've joined us!
