My husband was diagnosed in 2012, and I've been his sole caregiver for a long time.
I'm far from perfect, but I always try to keep my patience in check. After all, he can't help it.
I miss being able to just sit and talk. So when he keeps asking the same question over and over, I think of it as his way of trying to engage in a conversation, and I try to answer as if it's my first time. I'm not always successful, like all of you, I'm tired!!!
