Something similar happened to someone that I know. I'm a lifelong stutterer, but its very mild, unless I make a big deal out of it. Let me tell you nobody cares if you stutter on few words (nobody that matters that is). But every time you let that get into your head, that monster will grow bigger and bigger and bigger, until its too big to control. Over time, you inadvertently train your sub-conscious that you're afraid of speaking. Then comes anxiety, and then things really go downhill. I'm speaking from experience as someone that had mild stutter till my college years. I was very confident andn outgoing and never really cared about my stutter. But somehow after getting into my professional career, I started caring about the little tics, blockages, and stutters in my voice. The more I cared, the worse it became, till it consumed me completely. Lived with abject fear, anxiety andn self-loath for the next 15 years. The worse thing is during that time, nobody probably cared that I stutttered. I'm 40 now, and it took me 2 years of hard work and professional help to reverse those insecurities from my head. Don't be like me. We all have little imperfections. Don't let those ruin your fucking day....
