If dieting was easy, we'd all be size zeros - although after watching supersize/superskinny last night, i think i would rather just stay as i am than be a size zero
At least this way i keep my curvy womanly figure! But anyway, stress and dieting are such a difficult combination and it is what got me off the rails 2 months ago, i work for a local authority and while my job isn't currently at risk a number of colleagues are which is difficult to watch as they are friends as well... With the low self esteem, have you ever tried tackling it alongside the weight loss by seeing a counsellor? I remember when i lost a load of weight a few years back and was a healthy weight i still had all the self esteem problems - sometimes we think that losing the weight will give us back our self esteem but really it masks other underlying issues... Also i read about this book called the Beck book on another thread, not sure if you have heard about it but it is based on CBT therapy (which is very evidence-based!) and other people are finding it useful to tackle their "inner demons"
I really do hope things pick up for you really soon, in the meantime, why don't you draw a picture of what you think things will look like when you get to goal, what will be different? (or words if you are not artistic), then come up with a list of the small steps you need to get to this future you, that way you can cross them off as you go along and be reminded of all the successes you have had, rather than focussing on what you perceive are the failures - but while you are on this road there are no failures, just curves in the road.
Well done on all you have achieved so far and hope you have a better rest of the week xx
