You have the words exactly as you want them but when you open your mouth it’s if someone else is speaking and they’re usually an idiot. 
It’s not a mental health condition but more of a marble condition. Somehow those perfect words come out through the wrong side of your body and you appear as a 3 letter word instead. Take some comfort in knowing that it happens to us all sometime, somewhere and maybe that you can be grateful it didn’t occur when you were most famous. Someone else speaking from your mouth a condition we all have to go through let’s just hope they leave from the back entrance and don’t come back anytime soon.
