Chronic pain is a nasty thing and can knock the best laid plans of mice and men.
I think that is what threw me in May, an old back injury was playing up and making me miserable. It was all I could do to cope with the pain let alone start or maintain a VLCD. They dont call it comfort eating for nothing.
Be as sensible eating as you can and not use it as an excuse to have a free for all. You are not a massive failure at all, and you would not even think of saying that to another person! Just a thought whilst your body is going through this trauma might it be best to eat sensibly rather than restart a VLCD ?
Hope you get better soon. Pain is a miserable thing x
