I get grossed out by my own poop

I never get grossed out by my own shit before but this month, it happened. It all began when I looked down as they swam around the surface of water. Some of them floated down. They're like Davey Jone's cracked ship finding a way back home that it scared me with their brown, unamusing colour. How do I overcome this? I tried to not looked below but there's a whisper in my head telling me to do so.
