So I have something on my mind thats bothering me. So today I went over to my dad's house for my step-sisters graduation. She is 18 a good kid reminds me of me. Her sister my other step-sister shows up who is 20 who has been in and out of hospitals for bilemia and annorexia. She has been in out for nearly a year and half. She shows up today and can't weigh more than 75 pounds and I'm not really sure how she is alive her thighs are no bigger than my arms and I have pea shooters for arms. 1st I don't understand how a place like that lets someone go home when they look like that. 2nd I don't understand the disease its self. She has stole around $9,000 dollars of stuff of my dads and sold on ebay. How do you let yourself be that sick? Doesn't she notice the looks she gets and there not good looks there looks of disgust. I actually left my dads today because i felt sick just looking at her it was seriously like a balloon head on top of sticks. Let me know if you can give me any advice?
