Hi Louise and welcome to 3FC and the 100 lb club. A GREAT place to be!
Without a doubt finding something that we can indeed stick with LONGTERM is the big old key to weight loss success. Diets stop and start. We need something that continues, on and on and on. So therefore it is VITAL to find something that we can STICK with. It's all about forgetting the word "diet" and incorporating lifetime sustainable habits into our lives. Which means coming to the realization that we simply can not have it both ways. Yup. The high calorie/high quantity food has got to go. But there are lots of wonderful things to add - low fat proteins - such as chicken, turkey, cottage cheese, fat free yogurt, eggs, etc. Filling up on tons of veggies (finding new ones and new methods of cooking them, numerous salads, scrumptious fruits and grains.
As for the chinese food, well........ it just may be that you're better off without it for awhile. You can make your own chinese at home though. This way you know EXACTLY what's in there.
As for the motivation, I agree with Faerie, motivation comes and goes and is never around when we really need it. It's COMMITMENT that we need. You need and make that commitment, that no matter what, you are going to get and stay at a healthy weight. Once you make that commitment, losing weight IS doable and anyone, absolutely anyone CAN do it. I wish you tons of good luck.
And welcome to you too
