''you hate me because i'm fat''

I remember when I was a little girl, maybe 7 or 8, me and mum had an arguement - I don't remember what about, but I remember crying for hours and eventually writing her a note which said 'You hate me because I'm fat don't you?'. I remember it so very clearly. The genuine dispare that my mother hated me because I was 'fat' < at age 7 i was average > Today, my mum did not want to go out with me, did not want to spend any time with me, said she was busy then sat playin games on her android tab. I am that little girl again. The feeling is so real and so devestating.
