My husband, aged 69 yrs, was diagnosed with Alzhemiers 3 yrs ago. He attends a day client programme 3 x week so I do get some respite, but other than that he needs someone with him 24/7. Needs help with just about everything and get no conversation out of him. I am managing ok and family and friends are very supportive, however I find the evenings especially so long and lonely. I am only 69 yrs also, and only so many jigsaws, crosswords, etc. I can do! How do other people in my situation fill their evenings and keep their sanity!
Some have some relief hired in so they can go out to social, community, church function, volunteering.
Gardening.
Fostering a pet.
Cooking, or watching cooking shows.
Reading and podcasts.
I mean the world is full of things to do, and it is a matter of what interests you.
There may come a day when you wish to be more active and you cannot continue to care for hubby at home. That may never come if you get some in home help. Or some just do things inhome, such as above.
I wish you the best of luck, but we all have to try to find our own way. Art, collage, poetry, whatever interests you. Perhaps write the next great American mystery. Or memoir.
