Sending you a hug. I found it hard to see my relatives becoming older and frail too
Depending on how you feel about photos at the moment (some people find them comforting although some find them hard for a while), it may help to get older photos out, and bring to mind all those wonderful memories. Just like a book, we are so much more than the full stop at the end, we can remember all the vitality they had. I find it comforting to look at photos of when my grandparents were young, the happiness in their faces.
