I would love to hear your story - I know EXACTLY how you feel... What a huge difference it can make if you have a chance to share your experience - nowadays I spend hours on this site every night just reading the stories, learning something new every day, gathering positiveness for the following day, not to give up. And believe me, when I read success stories (about cancer for example), it gives me a huge boost, I feel like my problem is so tiny compering to theirs, it would be shame of me if I would fail when they succeeded... :)
I try to take it day by day. About this diet, I just say: I want to eat right TODAY. If I would think about eating right in the next 6 months (not to mention the rest of my life...), it would be a different story. :)
If you feel like, try it: look around this site, it's filled with positivness and open-mindedness - it will help you to discover yourself!
Best wishes. :)
