I can't follow the 6-week plan

I think I develop eating disorders when I try to diet or follow diet plans.  I wanted to follow Dr. Fuhrman's 6-week Eat to Live plan because I would like to become a "Certified Eat for Health Counselor."  I figured if I'm going to advise people, I should be able to follow the plan myself.  My plan was to start Jan. 1.  So I over-indulged before that, mostly on healthy stuff, but still, it was more than I normally care to eat (as my posts at the time show).  Then I did pretty well for a few weeks, but I occasionally overindulged on nuts.  And I've been tempted by things I never really cared for in the past, like baked goods.  Why did I not care for them in the past?  Because I felt kind of yucky after eating them.  I mean, I would eat some occasionally but I didn't crave them.  So I'm tired of trying to follow a plan, as it's too much mental work.   I'm just going to go back to my way of eating, which, ironically, is the Eat to Live plan, but with more nuts and seeds and fruits and dried fruits if I want them, since I don't need to lose weight.  It's just weird psychology that I can't diet or follow a plan, but if I don't follow it, then I can follow it.  When I was about 18 years old I started dieting, because I noticed I was gaining weight, and over the next few years I gained about 20 lbs.  I would say I had something of an eating disorder, along with most other women in my college dormitory--we would eat a bag of Oreo cookies and say, tomorrow I will start my diet!   Then my senior year I got tired of it and didn't care about my weight and I lost 20 lbs and stayed a healthy weight until my late 3os when I started gaining a couple of lbs a year like everyone else from the Standard American Diet (SAD).  

So I seem to be in a similar situation, though I have no desire to eat a bag of Oreo cookies, fortunately.  But I didn't like how I would eat too many nuts and say, okay tomorrow I'll start over, and then I would eat more than I even wanted, like it's my last meal.  I don't want to waste mental energy on this silliness anymore.  I'm not starting over with anything and I'm not going to deny myself anything.  As a vegan, I don't feel like I'm denying myself meat.  I just don't want it.   I'll just have to tell my clients that I can't follow a plan myself, but I still manage to eat healthy as if I am following a plan.  I'm sure that will make perfect sense to them, haha.
