Speak

I site here night after night yearning to speak. My mouth burning from everything I want to say yet when I open my mouth dust comes out. I close my mouth only to feel the burning again I open praying the flames would realize only to feel the dust on my lips. How can this burning to speak come on so strong for nothing to come out of it? The only thing to come from it is the occasional "I am fine" the ya's and ok's to move along the conversation so the other person thinks I am listening to them. Is it because I am surrounded by selfish stories about trivial things and every time I bring up my story if turns to dust on my lips like the burning to speak.
