My father passed away a long time ago, when I was still a child. My mother is getting older and it's really hard to see her weakening and having less capacity to do things she always did herself before. It's hard for her also as she is actually an independent person, which is great.

I am feeling the same way.  I luckily have a brother and a sister that will help me in taking care of my parents.  My wife is the only one here and it's going to be hard on her.  For me it's just something I will do.

I agree that it is somewhat shocking, and most often comes at the most inopportune timew in our lives. Maybe we should begin with a meeting with siblings.
