Garraway – who shares two children Darcey, 15, and William, 11, with Draper – filmed her husband’s journey.
The footage was broadcast last night as part of the powerful documentary Kate Garraway: Finding Derek.
During the hour-long film, broadcast on ITV last night, Garraway said she had “grieved” for her husband and the life they had together before.
“There’s been times where I’ve thought: ‘Am I actually grieving for the person I’m married to or am I fighting to hold onto that person?’”
In footage filmed in November 2020, Kate was asked if she had considered whether her husband might “not [be] her Derek” once he is out of hospital.
To which the presenter admitted: “Well, he is still Derek, he is still him… he is still that person that you love, but he will behave differently and will be physically different.
“Will I be okay? I wont be delighted because I wouldn’t wish that on him, very tough on us both, but he is for better or worse…”
She continued: “It might be a rather beautiful thing, trying to look at it as a rather beautiful thing. I feel as though we might have to fall in love again – find out who each other are now a little bit.”
Ben Shephard, Garraway’s Good Morning Britain co-star, said he is “so proud” of her as she “continues to surprise, delight, occasionally infuriate but always inspire me”.
He added: “Thinking of Kate, her family and anyone who is battling Covid or has lost someone close to them to the virus.”
Lorraine Kelly tweeted: “Heartbreaking but such courage, humanity and strength @kategarraway – you are incredible!”
Ms Garraway had earlier thanked fans for their support.
She said: “Thank you so much for all your lovely comments – your support means so much to me and others.”
