TheOriginalFAB you said you have issues with food. I totally understand. I do too. I have struggled for years with diets, losing, putting on etc etc.
All I can recommend is that you look into some books that will help you with your eating, help you to work out what the issues are and how you can change what you do. You said you managed to control your eating twice before, when was that and what was the key for you? Maybe the slimming pills will help but I do think getting to the bottom of the issues will help.
If it were possible to see a counsellor (which you may be able to get to see with a referrel from your GP) that might help.
I agree with LuckyC that there are a whole load of reasons why food now is a problem for lots of us. Some food is addictive. The kind that is addictive is the kind that is unhealthy but tastes good! This kind of food was not available to previous generations. So there are lots of issues we are facing that older generations did not have to contend with.
Please, please also stop beating yourself up, you are NOT crap. You are human and lots of people struggle with food. Learning to love yourself more and nurture yourself in a good way will help. Pamper yourself without food. a lovely relaxig bath with bubbles, some nice hand cream, some time to yourself whent3 the kids are in bed, a good magaizne. I know times re tight but food costs to and if you are overeating you may be spending that money on food which does not make you feel better could go to occasional non-food treats that may help you feel more positive.
You mentioned people you want to stick two fingers up at, can you find some way of working through those issues?
Finding ways of exploring what these food issues are working through them could be the key. I really hope it will.
If sharing helps, please do come back and share if you wish. I know how you feel. I have a lot to lose and it is very difficult but you must try and do it because you are lovely and worth it, not because of any negative feelings about yourself.
