Yeah when I was 14. They got me to play with lego... fucking ridiculous. I stopped and last year decided to try psychotherapy which was amazing. I learnt a lot about the mind but it was costing me £75 a week and at the time I was in school still and couldn't afford it. The biggest factor is fear and anticipation of failing. For example if I know I have a situation coming up where I will need to speak I am much more likely to stutter because my mind is constantly playing it over in my head. Whereas if suddenly I have to explain something for example I am much less likely to stutter because I have much less time to panic. Problem is, those feelings are almost impossible to control. -Phone broke, apologies for the late reply.
