  2. I am a 60yrs. old, white female. I have been an Anorexia all my life, due to being told, “I was too fat”. Now I am as skinny as a rail. Now I am too thin in peoples’ eyes’. When does it all end? I simply am scared to eat. When I do get comfortable eating right, someone in my husband’s family, just has to pull be back down. So now, I do not eat.Death will come for me, I am sure of it now. I Pray these people will “shut UP” when I do pass on to Glory, because it WILL be their Fault. All I ask, You so called ” Know It All” out there, keep your thoughts’ to your self. Too late for me, maybe NOT for someone else. Thank You Kindly, In Christ, Teri Ann Mayo 3:43pm 12/18/2016

  6. im 13, ’bout 5’0 and 45 kilos. i always feel overweight, considering how skinny my other friends are. my siblings call me fat, but you know how siblings are. plus my 2 older siblings look so much skinnier then me, and they’re 19 and 20. my 19 year old sister weighs 4 kilos more then me, so i always feel fat.
