What would you do with this kind of nightmare sibling?

you need to speak to an attorney to find out what your rights are when it comes to the property however i strongly recommend you leave that property and live on your own. this person sounds very unstable and you are in physical danger. do not wait. leave. you do not have to put up with this person. no one should live this way. please. move away from her. once she is away from you she will begin to make promises that she WILL NOT keep. cut this person out of your life. take care.
