Hello from a newbie!

Hello everyone. I am on step four of the program. I have no problems taking my vitamins every day, but I am still having problems with step three. (I was already taking the vitamins before reading the book, so I'm not skipping steps! I know that is not a good way to do this). I just wake up some days and feel like everything is too hard. It's too hard to "worry" about everything: what I eat, when I eat...blah blah. I feel like some days are just too hard to stick to it. I try to pick myself up the next day and carry on. I guess I just want to know that I am not alone. These steps are deceptively simple, and I feel like it should be easier. At least when you are doing something like quitting smoking you know it should be really hard. I have been over weight and addicted to sugar for years. I just feel like I am at the point where I need to reach out for some encouragement.
Thank you all for such wonderful resources, and such a great community!
