She is 80 years old or close to it. She is now caring for her husband, who is going down the altzheimer's hole. He is still at home, not terribly lost yet, but she is becoming less able to leave him alone except for a very short period of time. She is trapped and becoming angry. She loves him and doesn't want to put him in a home, but she is trapped, and she is angry anyway. It's just the two of them, in a good sized house and a good sized yard. It's all on her, now.
Tough decisions are in her future. At least there are family members to lend a hand, though the closest ones are maybe 15 miles away. They aren't young, either.
It's just tough. But nothing is forever, right? Not the good times, not the bad times.
