My sociopathic sister asked me to come visit my mom for 4 days while she goes on vacation. My 87 yr old mom has been in a skilled nursing facility since she fell almost a month ago. I live out of state but am going to visit her for 4 days in a few weeks to help take care of her while my sister is away. My sister is an evil liar and backstabber, so just wanted to be aware of any ways I can avoid trouble. I'm a little concerned that since I have no authority as far as my mother's health or financial matters - my sister has total control of her - I can't be involved in medical decisions. I'm just trying to think of some pitfalls I could fall in to if I'm not prepared for them. Say an emergency arises and the doctors won't talk to me since I have no healthcare authorization over her. So I will be excluded from any sharing of information or decisions but I am there overseeing her care. Or something happens - she falls out of bed, goes in to cardiac arrest, or whatever during my visit and I get blamed for it. I feel like I'm walking into a firestorm. Maybe I should bring a nannycam to record everything during my visits? Just trying to think of ways this visit could backfire on me. I'm not staying in her room, I am paying to stay in a guest room at the senior residence where her apt is. My sister said I could stay in my mom's apartment, but I don't want to leave myself open to accusations of theft and snooping. I have learned the hard way that it is a lot better to not even enter her apartment. If I do have to enter for any reason, such as my mom asks me to get something for her, I will have a security person accompany me as a witness. Sorry, I know this sounds paranoid, but I am dealing with a sociopath of a sister who stays up at night thinking of ways to trap and sabotage me. I don't speak to her except rare emails that are strictly business related to my mom. I am starting to have anxiety and second thoughts about going. I am a good person and would never do anything the least bit harmful, but my sister has made it her life's ambition to paint me out to be a bad person as a way to win favor with our mom and the rest of our family. Last visit there I was accused (after I left) of finding a watch my sister had lost and hiding it in my mom's financial document bag. I only found out a month later when my brother called me to let me know she was telling everyone that, and most believed her fabrication apparently. Any advise will be appreciated.
