the liver acts as a large filter for toxins. i had an aunt die of breast cancer that went to her liver/ brain and she did the same thing. her mental status was like your step dad. im glad he recognized you and was happy to see u. best wishes to u and your family. im sorry about the family pettiness. fear usually fuels it. its easier said then done for many people to not sweat the small stuff since most of life is the small stuff. im sorry about what is happening to u and your family... be looking for the updates.
