<human>: I'm an 18 year old male living in a wealthy New York suburb in Connecticut. My sister is 16. For a few years she has a had problems like cutting herself, anorexia and bulimia. She eventually had a severe mental breakdown and had to go to mental ward for nearly a weak. She took almost a month off from school and eventually transferred to a new school. At the end of summer she'll be attending another new school. She has made strides in the past few months I think because of medication and the therapy she has been receiving and I am very happy that she no longer cuts and will eat and not immediately throw up all the food. But, the way she treats our family is still horrible. She is verbally abusive to all of us and will often bring up her "disease" as a way to get out of doing anything she doesn't want to do. She also insisted on bringing us all to group therapy meetings which we were all receptive to at first but eventually just turned in to her telling us how bad we were and how it was our fault anything in her life went wrong. If she doesn't get her exact way she will sulk and act horribly unpleasant and ocassionally even threaten to cut again. My parents have essentially gone belly up at her feet because they say it is easier then arguing and dealing with an angry unstable teenage girl. My other sister, her twin, deals with the problem in much the same way. I still love my sister about half the time, but the other half of the time I hate her. I'm leaving for college in a month and I can't bear to imagine her keeping my family essentially hostage. I've seen what she does to my parents and I just can't stand it anymore! Reddit I need advice and guidance. Thanks.

<bot>: My sister is depressed but uses it as a way to get anything she wants. She treats my entire family horribly and I'm worried about what I should do.
