Well, not exactly childhood trauma and not exactly just one particular event. But I have stuttered since I was 7 years old. It was very overhelming year to me - my parents divorced, my grandfather died (very tragic for the whole family) and I started elementary school (oh, boy...). Since then I stutter. In my opinion there is large amount of people with the same start - especially this age particular. So don't worry, you certainly are not alone. I am very sorry to hear that from you - child abuse is fucking hell alone, and a stutter is something you do not deserve, I don't know your condition but I came through all the "classical" stuff - unability to talk through the phone, constant embarassements, traumatic events, better times, worse times. We've all been there - I, myself for almost 15 years. But I have heads up for you - it is treatable. And not by doctors - I (me and my mom) tried EVERYTHING. Treatments, logopeds, hypnosis (preaty awesome experience btw) but it did not get better. By the time I realised it's all about my psychical mood. It is always about the things that started you off - things that make you stutter. That weird feeling in your head that tells you that in next moments you'll not be able to talk. I learned how to manage those situation (and again, I don't know your condition) but you have to use skills that you KNOW you're good at. Use those skills and find your way how to communicate with people. That's how I managed to do it - I started tutoring (private teaching). After few years of working by speaking to people (and I find real passion in doing so) I realised my condition is rapidly better. Not 100%, but most of the times let's say 90%. Use your passion to overcome this. I don't want to sound like smart-ass or anything like that (I just had a nice day today so I am in mood to talk about stuff). I just want you to know that everything is managable. My doctors told me that if I wouldn't get rid of my stutter by the age of 15, I would be stuck with it for the rest of my life. Bullshit. You have to find your own way how to deal with it. Surround yourself with people that cares about you and find the way.
