I woke with diarrhea at 6:30 am. Now at around 11am I passed gas and experienced a lot of mucusy anal discharge. Should I be worried?

Infectious diarrhea. You clearly have an infectious diarrhea. Most resolve on their own, but it's important to stay hydrated. If it doesn;t get better on its own, or you cannot stay hydrated, then you may need to have IV fluids, which will mean a trip to the ER. Hope this Helps!
