is being monotone bad

I'm a bit monotone myself, and sometimes it's difficult to communicate with people when I need help or something important needs to be said.
So I always try hard to change but it sounds extremely exaggerated, reaching to a point to sound like a cartoonish character, but at least people can understand me better than before.
Try to exaggerated a little bit more. People will find extremely weird but they get used to it at some point.
