  1. I am 45 inches tall and im fourteen years old but i weigh 45kg is that good or bad and how much should i really weigh

  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
