I'm a newbie here but I thank you for your honesty in sharing your experience.
After my mom passed away three years ago (my parents were livings in Mexico) I had my dad move up here with me and my longtime boyfriend.
Conveniently, we owned two small houses next door to each other and instead of renting one we moved him in.
In the span of just these three years, Dad has done fewer and fewer things that he used to do. (He's 74 and in generally good health but has serious back problems that prevent him from standing for longer than a couple of minutes.)
I come over every morning before work for coffee with him and see him every afternoon. But now need to give him his pills or he doesn't take them. I nearly beg for him to change his clothes. He doesn't eat because he just isn't hungry. The basic conversations need to be had over and over because he forgets, although he can remember what he was wearing any day in 1968. He no longer drives but I'll take him anywhere he wants to go. But now he has trouble getting back into the house and hasn't gone anywhere in two weeks.
These are small tasks for me compared to what so many of you are dealing with but I don't have any experience with this.
Your stories and words make me laugh and cry. Thank you for your honesty and willingness to share.
