She is a control freak and wants my mom to make her power of attorney. I take care of my mom who has dementia but is still totally coherent. I also live with my mom. My sister want to be MPO and cant stand that she is not. My mom wants to make my son who is 27 years old to make her decisions. I know he will do a wonderful job because he is reasonable and would not do anything unless it was in the best interest of my mom. In addition moms mobile home is in her name and my sisters name, Mom is leaving it to me and I have paid my sister money that she had paid. She will not change the names on the title, which should be in my name only now in case she will end up in a nursing home. Neither one of this wants this, but sister does. I am so distraught over my sister and what she does and says that I am a total wreck. I know this is long but I need to vent and maybe some of you can give me some advice.
