Aw, I'm sorry but that's a horrible thing for your mum to say! I've always felt like one cause of my eating disorder is my mum, she's always been skinny and people have complemented her on that. And when I hit about 14/15 years old I was a teeny bit fatter than her which made me feel RUBBISH. So if I overate I'd feel even more worthless and make myself sick....but recently I found out she had bulimia when she was my age too. Doesn't help that she keeps preaching about how I'm "ruining my body and my life"....double standards much

Don't try and please anyone. It's your body: not hers, so do what's best for yourself.
Changing the way you think about food is really good!! I'm trying so hard to do that right now. It's been either my worst enemy or my best friend. I'm OBSESSED with food. I think the main thing is
eat for yourself and figure out what triggers a binge and purge. I used to think it was because I was greedy but there's patterns of when I binge and purge. And lately I just binge to "fill up" and never enjoy the food.
Take care as well... I've messed up really badly in the past few months and have tons of deficiencies and feel rubbish all the time and have lost my period...etc. So try and keep safe. xx
