My mother had a sharp cognitive decline after the jab. I told her a joke a while back and she laughed, a big belly laugh :-)
Now I tell her the same joke every time we talk and she laughs so hard because she can’t remember the last time I told the joke. Stay positive. Stay strong. It sounds to me like now is the time for you to be the rock your family needs.
Nostr is with you bro. You got this.
