Dealing with disappointment

One of the things I am learning to deal with is disappointment.

I feel disappointed in myself this week because:

I feel as if I should have been able to 'control' myself better.
I feel as if I have wasted about 1 week when I could have been losing weight. (Not sure if I have or not as it's my not weighing week).
I feel as if there is not much point trying when I may end up putting it all back on.

A lot of these feelings come back to my need to totally control the eating/diet/logging situation or else completely fall off the wagon and give up. I find it frustrating that I am a total all or nothing person. I either am committed to the program, or I am not. There's not 'partial' with me. I find the whole idea of this all or nothing to be totally disturbing because I cannot see how it will work when it comes to the idea of maintenance. Does it mean that I have to be forever on a diet and forever logging?

I would be lying if I said I have not thought about the fact that I may not lose more weight and I may not reach my goal. Weeks like the one that has just passed lead me to that kind of thinking. 17.25 pounds in and I can feel that the novelty of logging, calorie counting and being in the weight loss/diet zone have completely worn off. Now it is a chore. This completely flies in the face of the fact I have lost the weight and my clothes are falling off me etc. Shouldn't that be a motivator in itself? Why isn't that enough to keep me from straying?

These feelings and situation are totally compounded by TOTTM - it's a difficult time for me. I have dreadful, really excrutiating periods with what seems like some kind of endometriosis/interstitial cystitis going on. My hormones are all over the place and the PMS runs pretty rampant. Being able to control myself in the face of this has proved too much. I just ended up giving in and eating what I wanted.

The part that really irks me is the fact that I have been dilly-dallying around this 165ish weight for a while... I feel that by now I should have moved on and be well away from it, but I know that if I am not careful, all this extra eating and not exercising is going to see me back at 165 and pretty much ready to throw the towel in.

So yes, I am disappointed and I am frightened. I don't want to be this weight... I feel really uncomfortable.
