the techniques don't help me to speak the words I wish to say. Nor does the "feeling" go. If I can't say a sentence then I can't say it no matter what I do with my breathing etc. Well if I can talk fluently when I'm on my own then there isn't anything physically wrong with my vocal chords. If it just started suddenly when I was 18 then it must be mental too. I have only ever suffered with silent blocks so it must be mental.
