Why is my mum so unsupportive?

well done for your efforts. sometimes people don't want us to succeed better than they have done, because it makes it look as though they have failed. the answer is probably to try not to discuss food or diets with her, just praise her for other things that she does or has done well. My mother doesn't believe what I say, then reads it in a magazine months later and tells me as though she thought of it.
