Tmi warning.... yellow stools?

I've read some horror stories online no less with no real help or advice. I noticed today that my stool around 4:00 was softer than normal and was yellow. Then around 8:00 my entire abdomen hurt so bad. I had to run to the bathroom to go again and of course it was diarrhea and mustard yellow. I mentioned last week on a post about seeing what looked like meat fat in my normal stools and now this. I've researched and researched and found it could be my liver. Any other less freaky ideas?
