I am having a hard enough time being the only caretaker to husband with ALS of 46 years. My adult children don’t get along at all, both such different people. And one of them has a personality mental problem. that one will not believe that i love them both the same and they are 2 unique people. this one just brings arguements, conflicts and doesn’t help at all, even argues with her sick father then cries about losing him and i am in the middle. any suggestions?
