My father has been asking "who am I" more recently - and I'm worried he might end up losing his identity and convincing himself he is somebody else (he's been an actor his whole life).
He's also been expressing envy of me for being "younger".
Has this happened to anybody? and if so, how did you deal?
I would also put my energies into creating activities and distractions for him that give him a sense of purpose: pairing nuts and bolts, sorting screws or washers, sorting and pairing socks, chopping veggies for dinner, polishing silverware, whatever he is willing to do that is safe for him to do with minimum supervision. For my 99-yr old aunt we have her fold a large pile of kitchen towels. We emphasize that it would "really be helpful to us" if she'd do it and she always does. She folds the same pile several times a day. We also have her sort colored poker chips (because we had them already) and she makes them into patterns. She was a graphic designer and artist before she retired. She remembers some of us sometimes and not always accurately, and not a lot about herself or her life.
May you gain peace in your heart during this journey with your father.
