Maybe. I did go to therapy but mostly after the age of 20. My theory is that its to do with ur mental space. My brothers and father were confident men. Brother was afraid of talking coz of the stutter but he did school dances and performances etc. I've always been really shy and introvert and in the past few years i've become v socially anxious as well because of my increasing stammering. I've tried a lot to stay positive and went to a couple of therapists but it keeps getting worse.
