I recently discovered that my Aunt's mental state is rapidly declining. She lives alone in a senior, independent living apartment building. She is showing strong signs of dementia and is having trouble remembering how to do things like, unlock her car door before she gets out (she had to bang on her window until a stranger stopped to help her). She has not yet filed her 2017 taxes, which is something I know very little about. I never expected to have to take care of this Aunt, who I have never been very close with. But it appears the job will fall to me and I am clueless as how to proceed, especially with regards to her finances and helping her this tax season, as April 15 is rapidly approaching.
