I understand how you are feeling! My band was fitted in June 2011, and I've now gained 33 pounds back, which I've suffered with terrible panic and feelings of failure again. But I forget just how much I'd lost.
When you have the band in its all exciting and when the weight comes off you're discovering a new you...clothes etc...
What I forgot and didn't really recognise until recently is my bad attitide with food, and to learn a new healthy life style, and not have my teacher (the band) shout at me when I eat too much -and suffer.
I now know there's no magic wand, and the band helps restirict your quanities, but you have to do the rest, and change your habits. I think I understand it now and I'm getting over blaming the band for my failings, and to work with it! I will get these 33 pounds off this year and finish the job. I'm feeling more hopeful in myself.
