How do I know when it's not safe to leave my 89 year old mother alone. I've always been of the mindset that she should maintain her independence as long and as much as possible. Things may take her longer to do but as long as she can do them...I should allow her to do so. My mom has lived with me for 11 years. I work fulltime. I sometimes am gone overnight but I keep in close touch with her throughout the day, etc. I have a lifeline for her...but she has some dementia and doesn't remember what it is for. I help with everything (personal hygine, meals, meds, etc.) I feel we're on the tipping point but I don't know what the signs are. This hurts so much! I've tried to maintain my "mental health" as much as possible ... trying to balance some free time, etc. I'm at a loss right now. I want to do the right thing...hope I have up to now. Any suggestions would be helpful.
