Is it normal to feel kinda freaked out about this, "accident "?

I have have been acting as a live in caretaker for my parents who are in their 80s, and yesterday afternoon I had to help my father who had a diarrhea related accident, because he couldn't get to the toilet first. I was in my room on the phone with my sister when a heard sounds like someone fell down, and was screaming. When I got to the door of the master suite the smell hit me like a Mac truck! I found my 85 year old dad naked, soiled and on his hands and knees trying to clean the mess. I had to help him get up, and walk to the shower then my mom helped him get cleaned up in the shower. He almost fell down once.

This was not a pleasant experience, but honestly the worst thing was the smell, and the mess. I kinda always knew this day would come, I just didn't know which one of my folks would be first. I'm kinda freaked out.

All I could do was just help, try to keep my cool and reassure my dad that we love him. I also told him that I once peed my pants in a department store when I was seven years old.

This caretaker stuff ain't for sissies, and I should probably start going to the gym to try to build more muscle, because I'm gonna need it!
