Obsessive compulsive patterns of thinking about myself and my weight issues

I feel that even with weight loss there are some obsessive compulsive patterns of thinking.  If I fail even the slightest bit, then I might as well fail miserably.  That is a pattern of thinking I need to change.  I have I guess what I call a perfectionist complex.  Everything has to be just right or else it or rather I, could fall into pieces.  Weight loss is a journey and so is life.  My weight is only a part of who I am but I don't wish to stop or focus solely on my weight.  I have 90 more pounds to lose.  Daily I have to keep things in mind which can be easier said than done.  I am proud to have lost the weight that I have lost.  I am feeling so much better since I lost the weight.  I feel even more so since I exercised.  Those are two things that I keep in mind since I have exercised.  I know it was only yesterday but I am looking into the bright side of things.  It is  helpful to be positive when it comes to weight loss.  I have had low self-esteem issues as far as I can remember.  I believe that a positive attitude can take anyone who desires to lose weight a long way.
