My parents went into retirement with good health and ample savings, but a bad attitude toward aging. Isolation and depression settled in. My mom basically threw in the towel at 70 and declared she was "too old" to do anything. On her 75th birthday this year she stated that reaching the age of 75 was not something to strive for, it would be better to be dead (keep in mind this is a person with no health problems). She has become very toxic and I have had to build a firewall to protect my life from her negativity. I am an only child, she lives within walking distance, and will likely live for another 10-20 years. I feel like I am neglecting her but she is on the verge of ruining my life. I am 50 now. What if she lives until I'm 70? The thought of her trying to suck the life out of me for two more decades is horrible.
