Eleanor fell a year ago and her 2 neighbors approached her while she wasn't clear headed took advantage and made her sign to be her POA. She wants to revoke POA because their intentions are clear and it's to take as much as they can then put her into nursing home. They've stolen and continue stealing from her and they only care about Eleanor's finances. If she revoked them does she need a new POA? She doesn't have any kids or someone close to her who she could make her new POA. What is her best option?
