Stepdad and I are caregivers. Today is the second day of not eating. My mom has Alzheimers and I am her daughter. Only one of 6 kids that stepped in to help. My stepdad went away for a much needed break for 8 nights. Good for him I say. She has whined 24/7 since he has been gone. We haven't said when he is coming back only soon or in a day or so. Because I am the change in the house I get the brunt of her verbal bashings. Now she has decided not to eat. today is day 2 and still no food. I notice her complaining about something stuck in her throat several times a day. How long before i call a doctor and have him intervene?
