As a survivor of several strokes. . . .
I say this with all honesty. Fetterman needs to resign. He should never have been seated in the first place. A stroke on the scale of what he experienced, doesn't just affect you physically, it impacts you mentally and emotionally. You suddenly realize just how close your mortality can be. It changes you on may levels, and it certainly changed him. His struggle to regain his stamina and faculties was not a short or easy process. And he has not completely recovered and never will, his journey will continue. He should have taken the high road and had the grace to admit that he was NOT the person the people of PA elected and resigned.
I wish him all the best. He needs to focus on his health and his family should be the support network that encourages him to be honest with himself.
