<human>: A couple months ago, my sister came over and confessed that she had serious body image issues and had been throwing up. She tearfully told me she could "no longer control it" and needed help. What followed was a family intervention. We knew it was serious when my parents went up to visit her at school. After they had lunch, she literally sprinted ahead of my brother back to her house so she could throw up (he stood outside the bathroom and heard her).  To help her recover, we found her a specialist, set up an appointment, and off she went. After the first visit, she decided going to therapy was too inconvenient for her schedule, so she decided to bag it. This is in spite of promising the entire family she'd try to get help. After this incident, she canceled her trip home for Thanksgiving, saying she didn't want to be around the family during a holiday focused on eating. So, for the first time in her entire life, she wasn't with us for Thanksgiving because of eating issues. Now, Christmas is coming up and she'll be home for a month. She has forbidden any discussion of her "issues", claims my brother "misheard" that day after lunch and she wasn't throwing up, and insists that she's completely fine. So... bullshit? What should it take for her to convince us she really is fine?

Give me the gist of the text in a nutshell
<bot>: My sister threw up after eating for a while. Now that she has to spend a month at home, she claims she's fine and has no issues.
