Im sorry for what you are going through and your parents should step up and do something. Being the middle child is hard i know but you need to stand up for yourself. If your sister does not listen to reason and she really doesn't know what shes saying. She doesn't wish you were dead and i can honestly say this. If something were to happen to you and you ended up in the hospital or were injured i would bet she wouldn't be saying she wished you were dead. Sometimes people don't think about what they say or do or how it affects those around them. But you cant let it get to you and as far as for how she treats your friends that is really her problem not yours. When she realizes people wont hang around her because of how she acts she will either change or she will live alone. I hope things change on honestly this is your parents responsibility more then anyone else's. I think you should talk to them again.
