can i get a voice?

so the last few days ive been voiceless. on wednesday i had my usual class of 4-6 year olds and they were being very bad as usual. so i had to yell at them a bit to tell them to stop running headfirst into the wall or stop ripping apart my flashcards or stop stealing cookie monster puppet or stop using permanent marker on the whiteboard. turns out that since then i havent been able to talk too well. yesterday i basically had to apologize before each lesson about my voice...embarrasing when you tell students to repeat words after you when im whispering and they can barely hear what im saying or how to pronounce the words properly.

on the positive side, ive been told that it makes me sound like im a radio dj, so its not all bad.
