In India we don't have clubs. It's only in high end private schools. I'm preparing for JEE, and wouldn't be probably going to school anymore so it doesn't matter anymore. I don't have good ponds over here, I am only pushing them away from my life. I have a few friends, whom are hopefully not like that. Confidence can be an issue, but the problem is that I participate in several public speaking competitions and I usually do well. I only stammer during the start of my speech or statement, once I gain a flow I just go on and on like a rambling child. There are also times, when I feel like as if my tongue is stuck and I am not able to let air out of my lungs to speak. Recently I came across a new theory that my stammering might be related to low oxygenation levels in a specific reason of the brain. I don't excercise so it might be possible, I am planning to start sprinting. If low oxygenation levels is the case then high intensity interval training might solve it.
