Poor mom at nursing home

I am sad to see my mom living in nursing home for the past seven years. She refused to eat her medicine and she has temper that's why my dad decided to put her there. If she is out I fear of her safety too, she does not stay at home for long. She loves to go visit and my dad does not like at all. My mom has nine siblings and my grandma is living in old folk home. My grandma has diabetes and she no take medicine ended up blind. It is heart break seeing her like this. Being mom myself it is hurtful to see mom in this way. My mom often called me asking me to fetch her home to stay, but my dad and my dead do not agree. They worry she will not take her medicine and wonder outside. It is dangerous if she is out alone, we would fear of her safety. We cannot be 24/7 with her everyone has got things to do. I am not able to hire person to be with her and care her all time because I am just stay at home mom with no income. This Sunday will be gathering day because my bro is back from UK, she is excited to see him and thought he would bring her home to stay. Sad to say it is disappointing because they lied to her.
