Hang in there!
Remember, you've done it before and you can get "back on the wagon" and get back to losing weight. Even if you don't go to meetings as often/ever, you are still in control of what you decide to eat and how much you exercise.
I am currently on a variation of Ideal Protein, but I don't want to pay for their food. So I cut out all sugar (was really tough the first week.) And cut out as many carbs as they do on Ideal Protein.
I've lost about 11 pounds with no working out.
The nice thing is that now I'm starting to really get into a groove with my menu choices (lean protein, low carb shakes/bars, Walden foods dressings with my salads...)
I'm about to start jogging, which should really help break the plateau.
You can do it!
