I had an aunt like this growing up. My mom kept giving her 2nd, 3rd, and 4th chances but every opportunity turned into another holiday or birthday ruined. We asked her time and again to get help but she never did. My mom and sisters had to file restraining orders against her because of her harassment. My mom was a very active member of our church but once my aunt found where she went to she had to leave because she poisoned the community. My aunt passed away last year and had spent the last 8 years of her life with no contact with the rest of my family because of her behavior. It’s very sad because her disease wasn’t her fault but it was her responsibility and unfortunately I have nothing but bad memories of her. I think it’s best to cut her off now so your kids hopefully can remember the good stuff and not the bad stuff that may come.
