I also developed stuttering problem during my teens. Particularly, at 16 when moved to a new high school where unfortunately I wasn't very happy. I wasn't bullied or something like that, but because I was coming from a let's call it "lower social class" while all my classmates were relatively rich, I started feeling inferior to them. Then the stuttering appeared and that affected my performance in my studies. Before I go to that school I was a student of A's and wind up fighting for the bare pass mark in the new one. My issue was purely psychological, low self-esteem etc, and unfortunately it's still haunting me at the age of 36. Last couple of years though things are going quite well for me, my mental health is better than ever, and I made some progress with my problem. Now I stutter less than previously and I hope at some point to get rid of it completely. Some technical tips that I can give you to overcome the problem : - Breathing. Take deep breaths, that will calm you down and subsequently will relax your muscles. - practice at home by reading loud out. Grab a book and just read it and try to pronounce the words clearly -don't rush when you talk, go slowly. Usually, when we feel that stuttering is coming we panic and we try to say fast as many words as possible. That is wrong cause that makes us mumble in the end and people can not understand what we're saying -also very important is to raise your voice, not to shout but not to whisper as well. -last but not least, from my experience I can say that most people show empathy to our problem and they are not judging us if we stutter. Don't feel inferior because of that, we are different from others but it's not big deal. On the contrary, that is what makes us unique. I wish I had this approach earlier in my life, I'm sure things would have been better for my development as an adult and I wouldn't have the issues I struggled with all these years.
