I avoid contributing to group discussions even I have something valuable to say or if the discussion is going in wrong way, i just watch them discussing wrong things even I knew the truth, also my friends don't talk to me or they call me weird( yeah I heard many people calling that behind my back) because I don't talk to them even I want to talk, because of this fu***** stuttering that I know I'm gonna block many times, and simple sentence would take minutes to convey to them
