Can the police legally make someone leave their home when the home owner goes into a nursing home and is appointed a guardian?

I was living with an elderly friend to take care of her, never being paid, and she went to a nursing home and a guardian was appointed by the state. I lived there for almost a year. The sheriff came one day and made me leave. They said I was trespassing. I wasn't allowed to get any of my belongings and was told to contact the guardian. I have asked her 3 times to make arrangements with me so I can get my stuff from the property and I was told that she had to contact her attorney and she would call me and let me know. I have yet to receive a call to get my stuff. I've visited my friend in the nursing home several times and asked her if she was aware of the situation and she hasn't been told anything.
