Hello Eupatrid: There is a specific technique which can be used to assist with this problem. Basically, the "paradox" is that trying to "control yourself" is only making the problem worse. What you need to do is "not-control" yourself. I teach this, sooner or later, to almost all my students. You can look it up yourself on the Internet as "The Paradoxical Technique" or if you prefer, write to me, and I will send you something by E-mail, and may be able to work with you personally on the difficulty on Skype.--Warm Regards, Bruce

Just don't let your surrounding get to you, keep calm and maintain yourself. Take gaps when you speak, Or, have conversations with your family or close friends and ask for their opinion on your speaking and then take on board their feedback. :)

Think carefully of what you are going to say before you say it, so that you don't speak too many words at a time. :) Hope this helps.
