My mother and I have essentially put our lives on hold to take care of my terminally ill grandfather. We have family members who don’t want to respect my mother because she is disabled (they stated it to the police when we had to call the police on them). I had to call the police and file a report against one family member who attempted to attack my mother, and ended up fighting me. They’ve come over our house (which is actually my grandfather’s house but we live with him to take care of him) and have refused to leave. The police again had to be called to make them leave. They have called DHR on us claiming abuse (which was proven to be unfounded), they then called DHR again saying we were murdering my grandfather by over-medicating him with morphine (which was also found to be untrue). They then took me and my mother to court, but my mother was granted guardianship despite what they said. We had to pay money for a lawyer for this event as well. The court said they are allowed to visit between the hours of 10am-8pm. When they come in, they sneak in food to give to my grandfather (we’ve caught them), and then his hands/feet swell and WE have to answer to the nurse. They leave the door open for one another, so we don’t know who is coming in and out of our own house.
Can we sue them for mental anguish? It’s hard enough taking care of someone who is 85, has lung cancer, AND mesothelioma, then we have to worry about this. What can we do?
