Congrats you contributed to someone with an eating disorder. Because you did not reach out for help for your friend. She had no nutrients in her body and passed out this morning and had to go to the ER, so she won't be able to make it to prom. Maybe you wanted to win the game or just help a friend meet there goal. But really you just assisted in an unhealthy disorder. Over 30 million people in the US have eating disorders, you never know who that could be so instead of helping them engage in their disorder, help them fix it and find resources to help them.
