Being harassed, and rushed into selling my mother's home, which we shared for 48 years.

My mother died due to my sisters and brother's decision to not allow her to come home, and instead put her in Hospice, without any of her meds. Saw mom, she was sleeping, woke up, she started trying to take the IV and bracelets off her arm and told me to get her clothes, help her dress and that I had to sneak her out the back door, so no one could catch us. I would have, but didn't have a wheel chair. I didn't know what they were doing to her, and when I was leaving, my mom wanted to know why I could go home but she couldn't. I set up her escape for Wens. April 17th, had the wheel chair, a friend to help, and was about to call a cab, the phone rang and my other sister told me my mom had died. I lost it. Why, how??? Now, they are harassing me daily to sell the house, I and mom shared for 48 years, I was her only care giver, have document, signed by lawyer protecting me. Can't talk to lawyer due to no car, and constant RE agent in my home.
