Thank you all for your help and advice.
I am a regular but I use this name when I am discussing my 'issues' so yes, self-esteem, depression and various other things make my eating more problematic.
I do menu plan our main meal of the day but I think planning absolutely everything I will eat is a great idea too. I am good with lists and organization so I know I can do that. I have tried hard recently to keep occupied - go out, do stuff, be with people (but not where food is involved)
I like the idea of writing down what I didn't eat - I think that is something I can do now - keeping a log of emotions & eating behaviour is bit involved for me at the moment but I will definitely try to do that over the coming weeks.
I have borrowed a Low GI book from the library and I think I do a lot of it already but will read it and make sure I do it properly. It looks quite good so I am looking forward to making good meals again. And eating them properly.
It is so nice to hear from people who understand and have been through this and that it is something that can be controlled. I know I'll always struggle with this but I am so glad to hear other people get to grips with it and can lead a relativley normal life. Thank you SO much.
