Hey mate,I can completely relate to your struggles.Are you fluent in some scenarios like recording yourself alone or speaking to someone in particular?I think that it is imperative for you to experiment with your speech and identify the source of your troubles-emotional,psychological,etc.In my case I can speak flawlessly and spontaneously when recording myself or talking to my little sister,but any other circumstance is a nightmare.If you need someone to be empathetic and relate to your struggles,I am available.
