is it diarrhea or am i drinking too much water?

I just went to the bathroom because my stool felt like it was about to leak out, my stomach was gurgling and even though i passed quite a bit of stool, i still felt the need to pass, but nothing came out. I didn't leave the bathroom until 5 minutes later, when my anus had calmed down and i was able to get up without any problems.

What is this called? and what is the cause? I am drinking a bunch of water to soften my stool so any answer would be appreciated
