Hi there! I'm not on a VLCD myself so I hope you don't mind me posting here (just tell me to shoo!) - I just wanted to comment and say well done on your weight loss, wow!

Hopefully, like you say, this will motivate you and keep you going when it gets tough.
Reading Starlight's dairy is a great idea. I think also the mental attitude you have is important. It sounds like you are very worried at the moment (which is understandable) I am just wondering if it would help to switch your way of thinking.. instead of
depriving yourself from food you are giving yourself a
break from it. Like a rest from what you have been struggling with up until now.
Work out ways to relax, take it slowly, keep recording your weight, etc, and using that as motivation.
Which VLCD are you doing? Does it offer support that you can take advantage of? What is it that is scary for you?
And if you're finding it really impossible, is there the option of moving onto something else. For example, I'm doing slimfast and I eat 1 very reasonable meal a day as well as shakes for the other 2 and I am getting along well. Try and be flexible and realistic about what you can manage.

Not trying to sell it to you or persuade you in any way, just an example!
Take care. xx
