After our mother passed 54 years ago, our father remarried our stepmother. Our father passed several months ago, and the stepmother that we 3 children have known for 50 years now has advanced dementia, and can't recall events that occurred the day previous, is falling daily and can no longer care for herself. She has a 49 year old son with our father (our step-brother), but no one has heard from him in over 10 years, as he has chosen to go his own way and not stay in touch. Our stepmother does not want to give us any control to help her, but we are the only "family" she has left and someone needs to obtain POA, and medical POA because decisions need to be made and soon to get her help. She is not paying her bills, is forgetting to take medication, is falling and can't get up and is accidentally mixing pain medication and alcohol among other things. Since she no longer can cook for herself, we have cooked dinners sent to the house, but she can't find the food as she has forgotten what the refrigerator is for. How do we obtain POA, and can we do so if we are not "blood relatives". Time is running out. Thank you!
