Beth, I felt the same way you do. For probably 15 years, I just didn't try to lose weight at all because my previous attempts were so disturbing and humiliating to me ... lose a little weight, gain it back etc. etc.
There are many differences this time.
1. Community (the 3FC community). I also spend a lot of time reading about exercise, weight loss and goal setting.
2. A plan. I've changed tweaked my plan several times since I started, so I don't necessarily think the plan itself is the key, just that you HAVE a plan.
3. I judge myself by how well I work the plan, not by the scale. I know if I am working my plan, the weight will come off. If it's not coming off like I think it should -- I don't beat myself up. I look at my plan and see where I haven't been true to it.
4. Positive affirmations. I read Tom Venuto's "Burn the Fat, Feed the Muscle" and he believes -- and so do I -- that laying out your goals in a positive manner AND READING OR RE-WRITING THEM EVERY DAY is important.
Goals should be positive (NOT "I won't eat cake today" BUT "I am eating 5 small meals which include only good protein, veggies and fat.") You are really talking to your unconscious mind and it doesn't understand negatives, only positives in the present tense.
So, bottom line, I do think a positive attitude is key. And, for me, writing and reading my goals every day has kept me focused and believing I can do this.

I throw that in there because I just realized the rest of this post doesn't necessarily sound very pleasant.
